+
+===================
+Anatomy of a Plugin
+===================
+
+Plugins for Plugeth use Golang's `Native Plugin System`_. Plugin modules must export variables using specific names and types. These will be processed by the plugin loader, and invoked at certain points during Geth's operations.
+
+API
+***
+
+Flags
+-----
+
+* **Name:** Flags
+* **Type:** `flag.FlagSet`_
+* **Behavior:** This FlagSet will be parsed and your plugin will be able to access the resulting flags. Flags will be passed to Geth from the command line and are intended to  of the plugin. Note that if any flags are provided, certain checks are disabled within Geth to avoid failing due to unexpected flags.
+
+Subcommands
+-----------
+
+* **Name:** Subcommands
+* **Type:** map[string]func(ctx `*cli.Context`_, args []string) error
+* **Behavior:** If Geth is invoked with ``./geth YOUR_COMMAND``, the plugin loader will look for ``YOUR_COMMAND`` within this map, and invoke the corresponding function. This can be useful for certain behaviors like manipulating Geth's database without having to build a separate binary.
+
+Initialize
+----------
+
+* **Name:** Initialize
+* **Type:** func(*cli.Context, core.PluginLoader, core.logs )
+* **Behavior:** Called as soon as the plugin is loaded, with the cli context and a reference to the plugin loader. This is your plugin's opportunity to initialize required variables as needed. Note that using the context object you can check arguments, and optionally can manipulate arguments if needed for your plugin. 
+:ref:`Core vs Restricted packages in Plugeth-utils`
+
+**todo: explain that plugin could provide node.Node with restricted.backend**
+
+InitializeNode
+--------------
+
+* **Name:** InitializeNode
+* **Type:** func(core.Node, core.Backend)
+* **Behavior:** This is called as soon as the Geth node is initialized. The core.Node object represents the running node with p2p and RPC capabilities, while the Backend gives you access to a wide array of data you may need to access.
+
+Tracers
+-------
+
+* **Name:** Tracers
+* **Type:** map[string]TracerResult
+* **Behavior:** When calling debug.traceX functions (such as ``debug_traceCall`` and ``debug_traceTransaction``) the tracer can be specified as a key to this map and the tracer used will be the TracerResult specified here. TracerResult objects must match the interface:
+
+.. code-block:: go
+
+   ``// CaptureStart is called at the start of each transaction
+   CaptureStart(env core.EVM, from core.Address, to core.Address, create bool, input []byte, gas uint64, value *big.Int) {}
+   // CaptureState is called for each opcode
+   CaptureState(env core.EVM, pc uint64, op core.OpCode, gas, cost uint64, scope *vm.ScopeContext, rData []byte, depth int, err error) {}
+   // CaptureFault is called when an error occurs in the EVM
+   CaptureFault(env core.EVM, pc uint64, op core.OpCode, gas, cost uint64, scope *vm.ScopeContext, depth int, err error) {}
+   // CaptureEnd is called at the end of each transaction
+   CaptureEnd(output []byte, gasUsed uint64, t time.Duration, err error) {}
+   // GetResult should return a JSON serializable result object to respond to the trace call
+   GetResult() (interface{}, error) {}``
+
+
+.. warning:: Modifying the values passed into tracer functions can alter the
+             results of the EVM execution in unpredictable ways. Additonally, some objects may be reused acress calls, so data you wish to capture should be copied rather than retianed by reference. 
+
+LiveTracer
+----------
+
+* **Name:** LiveTracers
+* **Type:** core.Tracer
+* **Behavior:** This tracer is used for tracing transactions as they are processed within blocks. Note that if a block does not validate, some transactions may be processed that don't end up in blocks, so be sure to check transactions against finalized blocks.
+
+The interface for a vm.Tracer is similar to a TracerResult (above), but does not require a ``GetResult()`` function.
+
+GetAPIs
+-------
+
+* **Name:** GetAPIs
+* **Type:** func(core.Node, core.Backend) []rpc.API
+* **Behavior:** This allows you to register new RPC methods to run within Geth.
+
+The GetAPIs function itself will generally be fairly brief, and will looks something like this:
+
+.. code-block:: go
+
+	``func GetAPIs(stack *node.Node, backend core.Backend) []core.API {
+        return []rpc.API{
+         {
+           Namespace: "mynamespace",
+           Version:	 "1.0",
+           Service:	 &MyService{backend},
+           Public:		true,
+         },
+        }
+      }``
+
+The bulk of the implementation will be in the ``MyService`` struct. MyService should be a struct with public functions. These functions can have two different types of signatures:
+
+* RPC Calls: For straight RPC calls, a function should have a ``context.Context`` object as the first argument, followed by an arbitrary number of JSON marshallable arguments, and return either a single JSON marshal object, or a JSON marshallable object and an error. The RPC framework will take care of decoding inputs to this function and encoding outputs, and if the error is non-nil it will serve an error response.
+
+* Subscriptions: For subscriptions (supported on IPC and websockets), a function should have a ``context.Context`` object as the first argument followed by an arbitrary number of JSON marshallable arguments, and should return an ``*rpc.Subscription`` object. The subscription object can be created with ``rpcSub := notifier.CreateSubscription()``, and JSON marshallable data can be sent to the subscriber with ``notifier.Notify(rpcSub.ID, b)``.
+
+A very simple MyService might look like:
+
+.. code-block:: go
+
+	``type MyService struct{}
+
+	  func (h MyService) HelloWorld(ctx context.Context) string {
+	    return "Hello World"
+	  }``
+
+And the client could access this with an rpc call to 
+``mynamespace_helloworld``

+
+Setting up the environment
+**************************
+
+.. NOTE:: Plugeth is built on a fork of `Geth`_ and as such requires familiarity with `Go`_ and a funtional `environment`_ in which to build Go projects. Thankfully for everyone Go provides a compact and useful `tutorial`_ as well as a `space for practice`_. 
+
+PluGeth is an application built in three seperate repositories. 
+
+* `PluGeth`_
+* `PluGethUtils`_
+* `PluGethPlugins`_
+
+Once all three are cloned into their own directories you are ready to begin. First we need to build geth though the PluGeth project. Navigate to ``plugeth/cmd/geth`` and run:
+
+.. code-block:: shell
+
+   $ go get
+
+This will download all dependencies needed for the project. This process will take a moment or two the first time through. Next run: 
+
+.. code-block:: shell
+
+   $ go build
+
+Once this is complete you should see a ``.ethereum`` folder in your home directory. 
+
+At this point you are ready to start downloading local ethereum nodes. In order to do so, from ``plugeth/cmd/geth`` run:
+
+.. code-block:: shell
+
+   $ ./geth
+
+.. NOTE:: ``./geth`` is the primary command to build a *Mainnet* node. Building a mainnet node requires at least 8 GB RAM, 2 CPUs, and 350 GB of SSD disks. However, dozens of available flags will change the behavior of whichever network you choose to connect to. ``--help`` is your friend. 
+
+
+Build a plugin
+**************
+
+Navigate to ``plugethPlugins/packages/hello``. Inside you will see a ``main.go`` file. From this location run:
+
+.. code-block:: shell
+
+   $ go build -buildmode=plugin
+
+This will compile the plugin and produce a ``hello.so`` file. Move ``hello.so`` into ``~/.ethereum/plugins`` . In order to use this plugin geth will need to be started with a ``http.api=mymamespace`` flag. Additionally you will need to include a ``--http`` flag in order to access the standard json rpc methods. 
+
+Once geth has started you should see that the first ``INFO`` log reads: ``initialized hello`` . A new json rpc method, called hello, has been been appended to the list of available json rpc methods. In order to access this method you will need to ``curl`` into the network with this command:
+
+.. code-block:: shell
+
+   $ curl 127.0.0.1:8545 -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"mynamespace_hello","params":[],"id":0}'
+
+You should see that the network has responded with:
+
+.. code-block:: shell
+
+   ``{"jsonrpc":"2.0","id":0,"result":"Hello world"}``
+
+Congradulations. You have just built and run your first Plugeth plugin.

+PluGeth
+=======
+
+PluGeth is a fork of the `Go Ethereum Client Geth`_ that implements a plugin architecture, allowing developers to extend Geth's capabilities in a number of different ways using plugins, rather than having to create additional, new forks of Geth.
+
+**WARNING: UNSTABLE API**
+
+
+Right now PluGeth is in early development. We are still settling on some of the plugin APIs, and are not yet making official releases. From an operational perspective, PluGeth should be as stable as upstream Geth less whatever instability is added by plugins you might run. But if you plan to run PluGeth today, be aware that future updates will likely break your plugins.

+Design Goals
+
+The upstream Geth client exists primarily to serve as a client for the Ethereum mainnet, though it also supports a number of popular testnets. Supporting the Ethereum mainnet is a big enough challenge in its own right that the Geth team generally avoids changes to support other networks, or to provide features only a small handful of users would be interested in.
+
+The result is that many projects have forked Geth. Some implement their own consensus protocols or alter the behavior of the EVM to support other networks. Others are designed to extract information from the Ethereum mainnet in ways the standard Geth client does not support.
+
+Creating numerous different forks to fill a variety of different needs comes with a number of drawbacks. Forks tend to drift apart from each other. Many networks that forked from Geth long ago have stopped merging updates from Geth; this makes some sense, given that those networks have moved in different directions than Geth and merging upstream changes while properly maintaining consensus rules of an existing network could prove quite challenging. But not merging changes from upstream can mean that security updates are easily missed, especially when the upstream team `obscures security updates as optimizations`_ as a matter of process.
+
+PluGeth aims to provide a single Geth fork that developers can choose to extend rather than forking the Geth project. Out of the box, PluGeth behaves exactly like upstream Geth, but by installing plugins written in Golang, developers can extend its functionality in a wide variety of ways.
+
+Three Repositories
+------------------
+
+PluGeth is an application built in three repositories:
+
+`PluGeth`_
+**********
+
+The largest of the three Repositories, PluGeth is a fork of Geth which has been modified to enable a plugin architecture. The Plugin loader, wrappers, and hooks all reside in this repository. 
+
+`PluGeth-Utils`_
+***************
+
+Utils are small packages used to develop PluGeth plugins without Geth dependencies. For a more detailed analysis of the reasons see **here**
+
+`PluGeth-Plugins`_
+*****************
+
+Plugins are packages which contain premade plugins as well as a location provided for storing new custom plugins.

+System Requirements
+===================
+
+System requirements will vary depending on which network you are connecting to. On the Ethereum mainnet, you should have at least 8 GB RAM, 2 CPUs, and 350 GB of SSD disks.
+
+PluGeth relies on Golang's Plugin implementation, which is only supported on Linux, FreeBSD, and macOS. Windows support is unlikely to be added in the foreseeable future.

+.. _types:
+
+======================
+Basic Types of Plugins
+======================
+
+RPC Methods
+-----------
+
+In general these plugins provide new json rpc methods. They will requirre an initialize function that takes a context, loader, and logger as arguments. They will also need a GetAPIs function that takes a node and backend as arguments and returns an API. 
+
+.. NOTE:: In order to be made available a flag: ``http.api=<the name of your service>`` will need to be appended to the command line upon starting Geth. 
+
+Subcommand
+------------
+
+A subcommand redifines the total behavior of Geth and could stand on its own. 
+
+Tracers
+-------
+
+**Tracers vs LiveTracers. 
+
+Tracers rely on historic data whereas LiveTracers run concurent with Geth's verification system. LiveTracers are more generic in that they cannot control the way in which they recieve information. 
+
+
+Subscriptions
+-------------
+
+A subscription must take a context.context as an argument and return a channel and an error. Subscriptions require a stable connection and return contant information. Subscriptions require a websocket connection and pass a json argument such as: ``{"jsonrpc":"2.0", "id": 0, "method": "namespace_subscribe", "params": ["subscriptionName", $args...]}``
+
+.. NOTE:: Plugins are not limited to a singular functionality and can be customized to operate as hybrids of the above archtypes.

+<p>The bulk of the implementation will be in the <code class="docutils literal notranslate"><span class="pre">MyService</span></code> struct. MyService should be a struct with public functions. These functions can have two different types of signatures:</p>
+<ul class="simple">
+<li><p>RPC Calls: For straight RPC calls, a function should have a <code class="docutils literal notranslate"><span class="pre">context.Context</span></code> object as the first argument, followed by an arbitrary number of JSON marshallable arguments, and return either a single JSON marshal object, or a JSON marshallable object and an error. The RPC framework will take care of decoding inputs to this function and encoding outputs, and if the error is non-nil it will serve an error response.</p></li>
+<li><p>Subscriptions: For subscriptions (supported on IPC and websockets), a function should have a <code class="docutils literal notranslate"><span class="pre">context.Context</span></code> object as the first argument followed by an arbitrary number of JSON marshallable arguments, and should return an <code class="docutils literal notranslate"><span class="pre">*rpc.Subscription</span></code> object. The subscription object can be created with <code class="docutils literal notranslate"><span class="pre">rpcSub</span> <span class="pre">:=</span> <span class="pre">notifier.CreateSubscription()</span></code>, and JSON marshallable data can be sent to the subscriber with <code class="docutils literal notranslate"><span class="pre">notifier.Notify(rpcSub.ID,</span> <span class="pre">b)</span></code>.</p></li>
+</ul>
+<p>A very simple MyService might look like:</p>
+<div class="highlight-go notranslate"><div class="highlight"><pre><span></span><span class="s">``</span><span class="kd">type</span> <span class="nx">MyService</span> <span class="kd">struct</span><span class="p">{}</span>
+
+  <span class="kd">func</span> <span class="p">(</span><span class="nx">h</span> <span class="nx">MyService</span><span class="p">)</span> <span class="nx">HelloWorld</span><span class="p">(</span><span class="nx">ctx</span> <span class="nx">context</span><span class="p">.</span><span class="nx">Context</span><span class="p">)</span> <span class="kt">string</span> <span class="p">{</span>
+    <span class="k">return</span> <span class="s">&quot;Hello World&quot;</span>
+  <span class="p">}</span><span class="s">``</span>
+</pre></div>
+</div>
+<p>And the client could access this with an rpc call to
+<code class="docutils literal notranslate"><span class="pre">mynamespace_helloworld</span></code></p>
+</div>

+<p class="admonition-title">Note</p>
+<p>Plugeth is built on a fork of <a class="reference external" href="https://geth.ethereum.org/">Geth</a> and as such requires familiarity with <a class="reference external" href="https://golang.org/doc/">Go</a> and a funtional <a class="reference external" href="https://golang.org/doc/code">environment</a> in which to build Go projects. Thankfully for everyone Go provides a compact and useful <a class="reference external" href="https://tour.golang.org/welcome/1">tutorial</a> as well as a <a class="reference external" href="https://tour.golang.org/welcome/1">space for practice</a>.</p>
+</div>
+<p>PluGeth is an application built in three seperate repositories.</p>
+<ul class="simple">
+<li><p><a class="reference external" href="https://github.com/openrelayxyz/plugeth">PluGeth</a></p></li>
+<li><p><a class="reference external" href="https://github.com/openrelayxyz/plugeth-utils">PluGethUtils</a></p></li>
+<li><p><a class="reference external" href="https://github.com/openrelayxyz/plugeth-plugins">PluGethPlugins</a></p></li>
+</ul>
+<p>Once all three are cloned into their own directories you are ready to begin. First we need to build geth though the PluGeth project. Navigate to <code class="docutils literal notranslate"><span class="pre">plugeth/cmd/geth</span></code> and run:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>$ go get
+</pre></div>
+</div>
+<p>This will download all dependencies needed for the project. This process will take a moment or two the first time through. Next run:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>$ go build
+</pre></div>
+</div>
+<p>Once this is complete you should see a <code class="docutils literal notranslate"><span class="pre">.ethereum</span></code> folder in your home directory.</p>
+<p>At this point you are ready to start downloading local ethereum nodes. In order to do so, from <code class="docutils literal notranslate"><span class="pre">plugeth/cmd/geth</span></code> run:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>$ ./geth
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="admonition-title">Note</p>
+<p><code class="docutils literal notranslate"><span class="pre">./geth</span></code> is the primary command to build a <em>Mainnet</em> node. Building a mainnet node requires at least 8 GB RAM, 2 CPUs, and 350 GB of SSD disks. However, dozens of available flags will change the behavior of whichever network you choose to connect to. <code class="docutils literal notranslate"><span class="pre">--help</span></code> is your friend.</p>
+</div>
+</div>
+<div class="section" id="build-a-plugin">
+<h2><a class="toc-backref" href="#id3">Build a plugin</a><a class="headerlink" href="#build-a-plugin" title="Permalink to this headline">¶</a></h2>
+<p>Navigate to <code class="docutils literal notranslate"><span class="pre">plugethPlugins/packages/hello</span></code>. Inside you will see a <code class="docutils literal notranslate"><span class="pre">main.go</span></code> file. From this location run:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>$ go build -buildmode<span class="o">=</span>plugin
+</pre></div>
+</div>
+<p>This will compile the plugin and produce a <code class="docutils literal notranslate"><span class="pre">hello.so</span></code> file. Move <code class="docutils literal notranslate"><span class="pre">hello.so</span></code> into <code class="docutils literal notranslate"><span class="pre">~/.ethereum/plugins</span></code> . In order to use this plugin geth will need to be started with a <code class="docutils literal notranslate"><span class="pre">http.api=mymamespace</span></code> flag. Additionally you will need to include a <code class="docutils literal notranslate"><span class="pre">--http</span></code> flag in order to access the standard json rpc methods.</p>
+<p>Once geth has started you should see that the first <code class="docutils literal notranslate"><span class="pre">INFO</span></code> log reads: <code class="docutils literal notranslate"><span class="pre">initialized</span> <span class="pre">hello</span></code> . A new json rpc method, called hello, has been been appended to the list of available json rpc methods. In order to access this method you will need to <code class="docutils literal notranslate"><span class="pre">curl</span></code> into the network with this command:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>$ curl <span class="m">127</span>.0.0.1:8545 -H <span class="s2">&quot;Content-Type: application/json&quot;</span> --data <span class="s1">&#39;{&quot;jsonrpc&quot;:&quot;2.0&quot;,&quot;method&quot;:&quot;mynamespace_hello&quot;,&quot;params&quot;:[],&quot;id&quot;:0}&#39;</span>
+</pre></div>
+</div>
+<p>You should see that the network has responded with:</p>
+<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span><span class="sb">``</span><span class="o">{</span><span class="s2">&quot;jsonrpc&quot;</span>:<span class="s2">&quot;2.0&quot;</span>,<span class="s2">&quot;id&quot;</span>:0,<span class="s2">&quot;result&quot;</span>:<span class="s2">&quot;Hello world&quot;</span><span class="o">}</span><span class="sb">``</span>
+</pre></div>
+</div>
+<p>Congradulations. You have just built and run your first Plugeth plugin.</p>

+<h1>PluGeth<a class="headerlink" href="#plugeth" title="Permalink to this headline">¶</a></h1>
+<p>PluGeth is a fork of the <a class="reference external" href="https://github.com/ethereum/go-ethereum">Go Ethereum Client Geth</a> that implements a plugin architecture, allowing developers to extend Geth’s capabilities in a number of different ways using plugins, rather than having to create additional, new forks of Geth.</p>
+<p><strong>WARNING: UNSTABLE API</strong></p>
+<p>Right now PluGeth is in early development. We are still settling on some of the plugin APIs, and are not yet making official releases. From an operational perspective, PluGeth should be as stable as upstream Geth less whatever instability is added by plugins you might run. But if you plan to run PluGeth today, be aware that future updates will likely break your plugins.</p>

+<p>Design Goals</p>
+<p>The upstream Geth client exists primarily to serve as a client for the Ethereum mainnet, though it also supports a number of popular testnets. Supporting the Ethereum mainnet is a big enough challenge in its own right that the Geth team generally avoids changes to support other networks, or to provide features only a small handful of users would be interested in.</p>
+<p>The result is that many projects have forked Geth. Some implement their own consensus protocols or alter the behavior of the EVM to support other networks. Others are designed to extract information from the Ethereum mainnet in ways the standard Geth client does not support.</p>
+<p>Creating numerous different forks to fill a variety of different needs comes with a number of drawbacks. Forks tend to drift apart from each other. Many networks that forked from Geth long ago have stopped merging updates from Geth; this makes some sense, given that those networks have moved in different directions than Geth and merging upstream changes while properly maintaining consensus rules of an existing network could prove quite challenging. But not merging changes from upstream can mean that security updates are easily missed, especially when the upstream team <a href="#id4"><span class="problematic" id="id5">`obscures security updates as optimizations`_</span></a> as a matter of process.</p>
+<p>PluGeth aims to provide a single Geth fork that developers can choose to extend rather than forking the Geth project. Out of the box, PluGeth behaves exactly like upstream Geth, but by installing plugins written in Golang, developers can extend its functionality in a wide variety of ways.</p>

+<p>In general these plugins provide new json rpc methods. They will requirre an initialize function that takes a context, loader, and logger as arguments. They will also need a GetAPIs function that takes a node and backend as arguments and returns an API.</p>
+<div class="admonition note">

+<p>A subscription must take a context.context as an argument and return a channel and an error. Subscriptions require a stable connection and return contant information. Subscriptions require a websocket connection and pass a json argument such as: <code class="docutils literal notranslate"><span class="pre">{&quot;jsonrpc&quot;:&quot;2.0&quot;,</span> <span class="pre">&quot;id&quot;:</span> <span class="pre">0,</span> <span class="pre">&quot;method&quot;:</span> <span class="pre">&quot;namespace_subscribe&quot;,</span> <span class="pre">&quot;params&quot;:</span> <span class="pre">[&quot;subscriptionName&quot;,</span> <span class="pre">$args...]}</span></code></p>

+
+===================
+Anatomy of a Plugin
+===================
+
+Plugins for Plugeth use Golang's `Native Plugin System`_. Plugin modules must export variables using specific names and types. These will be processed by the plugin loader, and invoked at certain points during Geth's operations.
+
+API
+***
+
+Flags
+-----
+
+* **Name:** Flags
+* **Type:** `flag.FlagSet`_
+* **Behavior:** This FlagSet will be parsed and your plugin will be able to access the resulting flags. Flags will be passed to Geth from the command line and are intended to  of the plugin. Note that if any flags are provided, certain checks are disabled within Geth to avoid failing due to unexpected flags.
+
+Subcommands
+-----------
+
+* **Name:** Subcommands
+* **Type:** map[string]func(ctx `*cli.Context`_, args []string) error
+* **Behavior:** If Geth is invoked with ``./geth YOUR_COMMAND``, the plugin loader will look for ``YOUR_COMMAND`` within this map, and invoke the corresponding function. This can be useful for certain behaviors like manipulating Geth's database without having to build a separate binary.
+
+Initialize
+----------
+
+* **Name:** Initialize
+* **Type:** func(*cli.Context, core.PluginLoader, core.logs )
+* **Behavior:** Called as soon as the plugin is loaded, with the cli context and a reference to the plugin loader. This is your plugin's opportunity to initialize required variables as needed. Note that using the context object you can check arguments, and optionally can manipulate arguments if needed for your plugin. 
+:ref:`Core vs Restricted packages in Plugeth-utils`
+
+**todo: explain that plugin could provide node.Node with restricted.backend**
+
+InitializeNode
+--------------
+
+* **Name:** InitializeNode
+* **Type:** func(core.Node, core.Backend)
+* **Behavior:** This is called as soon as the Geth node is initialized. The core.Node object represents the running node with p2p and RPC capabilities, while the Backend gives you access to a wide array of data you may need to access.
+
+Tracers
+-------
+
+* **Name:** Tracers
+* **Type:** map[string]TracerResult
+* **Behavior:** When calling debug.traceX functions (such as ``debug_traceCall`` and ``debug_traceTransaction``) the tracer can be specified as a key to this map and the tracer used will be the TracerResult specified here. TracerResult objects must match the interface:
+
+.. code-block:: go
+
+   ``// CaptureStart is called at the start of each transaction
+   CaptureStart(env core.EVM, from core.Address, to core.Address, create bool, input []byte, gas uint64, value *big.Int) {}
+   // CaptureState is called for each opcode
+   CaptureState(env core.EVM, pc uint64, op core.OpCode, gas, cost uint64, scope *vm.ScopeContext, rData []byte, depth int, err error) {}
+   // CaptureFault is called when an error occurs in the EVM
+   CaptureFault(env core.EVM, pc uint64, op core.OpCode, gas, cost uint64, scope *vm.ScopeContext, depth int, err error) {}
+   // CaptureEnd is called at the end of each transaction
+   CaptureEnd(output []byte, gasUsed uint64, t time.Duration, err error) {}
+   // GetResult should return a JSON serializable result object to respond to the trace call
+   GetResult() (interface{}, error) {}``
+
+
+.. warning:: Modifying the values passed into tracer functions can alter the
+             results of the EVM execution in unpredictable ways. Additonally, some objects may be reused acress calls, so data you wish to capture should be copied rather than retianed by reference. 
+
+LiveTracer
+----------
+
+* **Name:** LiveTracers
+* **Type:** core.Tracer
+* **Behavior:** This tracer is used for tracing transactions as they are processed within blocks. Note that if a block does not validate, some transactions may be processed that don't end up in blocks, so be sure to check transactions against finalized blocks.
+
+The interface for a vm.Tracer is similar to a TracerResult (above), but does not require a ``GetResult()`` function.
+
+GetAPIs
+-------
+
+* **Name:** GetAPIs
+* **Type:** func(core.Node, core.Backend) []rpc.API
+* **Behavior:** This allows you to register new RPC methods to run within Geth.
+
+The GetAPIs function itself will generally be fairly brief, and will looks something like this:
+
+.. code-block:: go
+
+	``func GetAPIs(stack *node.Node, backend core.Backend) []core.API {
+        return []rpc.API{
+         {
+           Namespace: "mynamespace",
+           Version:	 "1.0",
+           Service:	 &MyService{backend},
+           Public:		true,
+         },
+        }
+      }``
+
+The bulk of the implementation will be in the ``MyService`` struct. MyService should be a struct with public functions. These functions can have two different types of signatures:
+
+* RPC Calls: For straight RPC calls, a function should have a ``context.Context`` object as the first argument, followed by an arbitrary number of JSON marshallable arguments, and return either a single JSON marshal object, or a JSON marshallable object and an error. The RPC framework will take care of decoding inputs to this function and encoding outputs, and if the error is non-nil it will serve an error response.
+
+* Subscriptions: For subscriptions (supported on IPC and websockets), a function should have a ``context.Context`` object as the first argument followed by an arbitrary number of JSON marshallable arguments, and should return an ``*rpc.Subscription`` object. The subscription object can be created with ``rpcSub := notifier.CreateSubscription()``, and JSON marshallable data can be sent to the subscriber with ``notifier.Notify(rpcSub.ID, b)``.
+
+A very simple MyService might look like:
+
+.. code-block:: go
+
+	``type MyService struct{}
+
+	  func (h MyService) HelloWorld(ctx context.Context) string {
+	    return "Hello World"
+	  }``
+
+And the client could access this with an rpc call to 
+``mynamespace_helloworld``

+Build
+=====
+
+.. contents:: :local:
+
+Setting up the environment
+**************************
+
+.. NOTE:: Plugeth is built on a fork of `Geth`_ and as such requires familiarity with `Go`_ and a funtional `environment`_ in which to build Go projects. Thankfully for everyone Go provides a compact and useful `tutorial`_ as well as a `space for practice`_. 
+
+PluGeth is an application built in three seperate repositories. 
+
+* `PluGeth`_
+* `PluGethUtils`_
+* `PluGethPlugins`_
+
+Once all three are cloned into their own directories you are ready to begin. First we need to build geth though the PluGeth project. Navigate to ``plugeth/cmd/geth`` and run:
+
+.. code-block:: shell
+
+   $ go get
+
+This will download all dependencies needed for the project. This process will take a moment or two the first time through. Next run: 
+
+.. code-block:: shell
+
+   $ go build
+
+Once this is complete you should see a ``.ethereum`` folder in your home directory. 
+
+At this point you are ready to start downloading local ethereum nodes. In order to do so, from ``plugeth/cmd/geth`` run:
+
+.. code-block:: shell
+
+   $ ./geth
+
+.. NOTE:: ``./geth`` is the primary command to build a *Mainnet* node. Building a mainnet node requires at least 8 GB RAM, 2 CPUs, and 350 GB of SSD disks. However, dozens of available flags will change the behavior of whichever network you choose to connect to. ``--help`` is your friend. 
+
+
+Build a plugin
+**************
+
+Navigate to ``plugethPlugins/packages/hello``. Inside you will see a ``main.go`` file. From this location run:
+
+.. code-block:: shell
+
+   $ go build -buildmode=plugin
+
+This will compile the plugin and produce a ``hello.so`` file. Move ``hello.so`` into ``~/.ethereum/plugins`` . In order to use this plugin geth will need to be started with a ``http.api=mymamespace`` flag. Additionally you will need to include a ``--http`` flag in order to access the standard json rpc methods. 
+
+Once geth has started you should see that the first ``INFO`` log reads: ``initialized hello`` . A new json rpc method, called hello, has been been appended to the list of available json rpc methods. In order to access this method you will need to ``curl`` into the network with this command:
+
+.. code-block:: shell
+
+   $ curl 127.0.0.1:8545 -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"mynamespace_hello","params":[],"id":0}'
+
+You should see that the network has responded with:
+
+.. code-block:: shell
+
+   ``{"jsonrpc":"2.0","id":0,"result":"Hello world"}``
+
+Congradulations. You have just built and run your first Plugeth plugin.

+PluGeth
+=======
+
+PluGeth is a fork of the `Go Ethereum Client Geth`_ that implements a plugin architecture, allowing developers to extend Geth's capabilities in a number of different ways using plugins, rather than having to create additional, new forks of Geth.
+
+**WARNING: UNSTABLE API**
+
+
+Right now PluGeth is in early development. We are still settling on some of the plugin APIs, and are not yet making official releases. From an operational perspective, PluGeth should be as stable as upstream Geth less whatever instability is added by plugins you might run. But if you plan to run PluGeth today, be aware that future updates will likely break your plugins.

+Design Goals
+
+The upstream Geth client exists primarily to serve as a client for the Ethereum mainnet, though it also supports a number of popular testnets. Supporting the Ethereum mainnet is a big enough challenge in its own right that the Geth team generally avoids changes to support other networks, or to provide features only a small handful of users would be interested in.
+
+The result is that many projects have forked Geth. Some implement their own consensus protocols or alter the behavior of the EVM to support other networks. Others are designed to extract information from the Ethereum mainnet in ways the standard Geth client does not support.
+
+Creating numerous different forks to fill a variety of different needs comes with a number of drawbacks. Forks tend to drift apart from each other. Many networks that forked from Geth long ago have stopped merging updates from Geth; this makes some sense, given that those networks have moved in different directions than Geth and merging upstream changes while properly maintaining consensus rules of an existing network could prove quite challenging. But not merging changes from upstream can mean that security updates are easily missed, especially when the upstream team `obscures security updates as optimizations`_ as a matter of process.
+
+PluGeth aims to provide a single Geth fork that developers can choose to extend rather than forking the Geth project. Out of the box, PluGeth behaves exactly like upstream Geth, but by installing plugins written in Golang, developers can extend its functionality in a wide variety of ways.
+
+Three Repositories
+------------------
+
+PluGeth is an application built in three repositories:
+
+`PluGeth`_
+**********
+
+The largest of the three Repositories, PluGeth is a fork of Geth which has been modified to enable a plugin architecture. The Plugin loader, wrappers, and hooks all reside in this repository. 
+
+`PluGeth-Utils`_
+***************
+
+Utils are small packages used to develop PluGeth plugins without Geth dependencies. For a more detailed analysis of the reasons see **here**
+
+`PluGeth-Plugins`_
+*****************
+
+Plugins are packages which contain premade plugins as well as a location provided for storing new custom plugins.

+
+System requirements will vary depending on which network you are connecting to. On the Ethereum mainnet, you should have at least 8 GB RAM, 2 CPUs, and 350 GB of SSD disks.

+PluGeth relies on Golang's Plugin implementation, which is only supported on Linux, FreeBSD, and macOS. Windows support is unlikely to be added in the foreseeable future.

+======================
+Basic Types of Plugins
+======================
+
+RPC Methods
+-----------
+
+In general these plugins provide new json rpc methods. They will requirre an initialize function that takes a context, loader, and logger as arguments. They will also need a GetAPIs function that takes a node and backend as arguments and returns an API. 
+
+.. NOTE:: In order to be made available a flag: ``http.api=<the name of your service>`` will need to be appended to the command line upon starting Geth. 
+
+Subcommand
+------------
+
+A subcommand redifines the total behavior of Geth and could stand on its own. 
+
+Tracers
+-------
+
+**Tracers vs LiveTracers. 
+
+Tracers rely on historic data whereas LiveTracers run concurent with Geth's verification system. LiveTracers are more generic in that they cannot control the way in which they recieve information. 
+
+
+Subscriptions
+-------------
+
+A subscription must take a context.context as an argument and return a channel and an error. Subscriptions require a stable connection and return contant information. Subscriptions require a websocket connection and pass a json argument such as: ``{"jsonrpc":"2.0", "id": 0, "method": "namespace_subscribe", "params": ["subscriptionName", $args...]}``
+
+.. NOTE:: Plugins are not limited to a singular functionality and can be customized to operate as hybrids of the above archtypes.
