+complicate data accessibility and usability for dApp developers. VulcanizeDB improves Ethereum data accessibility by
+providing a suite of tools to ease the extraction and transformation of data into a more useful state, including
+allowing for exposing aggregate data from a suite of smart contracts.

+VulanizeDB includes processes that sync, transform and expose data. Syncing involves
+querying an Ethereum node and then persisting core data into a Postgres database. Transforming focuses on using previously synced data to
+query for and transform log event and storage data for specifically configured smart contract addresses. Exposing data is a matter of getting
+data from VulcanizeDB's underlying Postgres database and making it accessible.

+Be sure you have enabled Go Modules (`export GO111MODULE=on`), and build the executable with:

 `make build`

+If you need to use a different dependency than what is currently defined in `go.mod`, it may helpful to look into [the replace directive](https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive).
+This instruction enables you to point at a fork or the local filesystem for dependency resolution.
+
 If you are running into issues at this stage, ensure that `GOPATH` is defined in your shell.
 If necessary, `GOPATH` can be set in `~/.bashrc` or `~/.bash_profile`, depending upon your system.
 It can be additionally helpful to add `$GOPATH/bin` to your shell's `$PATH`.

 ## Usage
-Usage is broken up into two processes:
+As mentioned above, VulcanizeDB's processes can be split into three categories: syncing, transforming and exposing data.

 ### Data syncing
-To provide data for transformations, raw Ethereum data must first be synced into vDB.
-This is accomplished through the use of the `headerSync`, `sync`, or `coldImport` commands.
-These commands are described in detail [here](../staging/documentation/sync.md).
+To provide data for transformations, raw Ethereum data must first be synced into VulcanizeDB.
+This is accomplished through the use of the `headerSync`, `fullSync`, or `coldImport` commands.
+These commands are described in detail [here](documentation/data-syncing.md).

 ### Data transformation
-Contract watchers use the raw data that has been synced into Postgres to filter out and apply transformations to specific data of interest.
+Data transformation uses the raw data that has been synced into Postgres to filter out and apply transformations to
+specific data of interest. Since there are different types of data that may be useful for observing smart contracts, it
+follows that there are different ways to transform this data. We've started by categorizing this into Generic and
+Custom transformers:

-There is a built-in `contractWatcher` command which provides generic transformation of most contract data.
-The `contractWatcher` command is described further [here](../staging/documentation/contractWatcher.md).
+- Generic Contract Transformer: Generic contract transformation can be done using a built-in command,
+`contractWatcher`, which transforms contract events provided the contract's ABI is available. It also
+provides some state variable coverage by automating polling of public methods, with some restrictions.
+`contractWatcher` is described further [here](documentation/generic-transformer.md).

-In many cases a custom transformer or set of transformers will need to be written to provide complete or more comprehensive coverage or to optimize other aspects of the output for a specific end-use.
-In this case we have provided the `compose`, `execute`, and `composeAndExecute` commands for running custom transformers from external repositories.
+- Custom Transformers: In many cases custom transformers will need to be written to provide
+more comprehensive coverage of contract data. In this case we have provided the `compose`, `execute`, and
+`composeAndExecute` commands for running custom transformers from external repositories. Documentation on how to write,
+build and run custom transformers as Go plugins can be found
+[here](documentation/custom-transformers.md).

-Usage of the `compose`, `execute`, and `composeAndExecute` commands is described further [here](../staging/documentation/composeAndExecute.md).

-Documentation on how to build custom transformers to work with these commands can be found [here](../staging/documentation/transformers.md).

+### Tests
 - Replace the empty `ipcPath` in the `environments/infura.toml` with a path to a full node's eth_jsonrpc endpoint (e.g. local geth node ipc path or infura url)

+* Separate `compose` and `execute` commands allow pre-building and linking to the pre-built .so file. So, if

+    environment, i.e. we need to `compose` and `execute` the plugin .so file with the same exact version of vulcanizeDB.
+    * The plugin migrations are run during the plugin's composition. As such, if `execute` is used to run a prebuilt .so
+    in a different environment than the one it was composed in, then the database structure will need to be loaded 
+    into the environment's Postgres database. This can either be done by manually loading the plugin's schema into 
+    Postgres, or by manually running the plugin's migrations.
+     
+* The `compose` and `composeAndExecute` commands assume you are in the vulcanizdb directory located at your system's 
+`$GOPATH`, and that the plugin dependencies are present at their `$GOPATH` directories.

+# Syncing commands
+These commands are used to sync raw Ethereum data into Postgres, with varying levels of data granularity.
+
+## headerSync
+Syncs block headers from a running Ethereum node into the VulcanizeDB table `headers`.
+- Queries the Ethereum node using RPC calls.
+- Validates headers from the last 15 blocks to ensure that data is up to date.
+- Useful when you want a minimal baseline from which to track targeted data on the blockchain (e.g. individual smart
+contract storage values or event logs).
+- Handles chain reorgs by [validating the most recent blocks' hashes](../pkg/history/header_validator.go). If the hash is
+different from what we have already stored in the database, the header record will be updated.
+
+#### Usage
+- Run: `./vulcanizedb headerSync --config <config.toml> --starting-block-number <block-number>`
+- The config file must be formatted as follows, and should contain an ipc path to a running Ethereum node:
+```toml
+[database]
+    name     = "vulcanize_public"
+    hostname = "localhost"
+    user     = "vulcanize"

+[client]
+    ipcPath  = <path to a running Ethereum node>
+```
+- Alternatively, the ipc path can be passed as a flag instead `--client-ipcPath`.
+
+## fullSync
+Syncs blocks, transactions, receipts and logs from a running Ethereum node into VulcanizeDB tables named
+`blocks`, `uncles`, `full_sync_transactions`, `full_sync_receipts` and `logs`. 
+- Queries the Ethereum node using RPC calls.
+- Validates headers from the last 15 blocks to ensure that data is up to date.

+transactions, receipts and logs into VulcanizeDB tables named `blocks`, `uncles`, 
+`full_sync_transactions`, `full_sync_receipts` and `logs` respectively.
+
+#### Usage

+# Postgraphile
+
+You can expose VulcanizeDB data via [Postgraphile](https://github.com/graphile/postgraphile).
+Check out [their documentation](https://www.graphile.org/postgraphile/) for the most up-to-date instructions on installing, running, and customizing Postgraphile.
+
+## Simple Setup
+
+As of April 30, 2019, you can run Postgraphile pointed at the default `vulcanize_public` database with the following commands:
+
+```
+npm install -g postgraphile
+postgraphile --connection postgres://localhost/vulcanize_public --schema=public,custom --disable-default-mutations --no-ignore-rbac
+```
+
+Arguments:
+- `--connection` specifies the database. The above command connects to the default `vulcanize_public` database 
+defined in [the example config](../environments/public.toml.example).
+- `--schema` defines what schema(s) to expose. The above exposes the `public` schema (for core VulcanizeDB data) as well as a `custom` schema (where `custom` is the name of a schema defined in executed transformers).
+- `--disable-default-mutations` prevents Postgraphile from exposing create, update, and delete operations on your data, which are otherwise enabled by default.
+- `--no-ignore-rbac` ensures that Postgraphile will only expose the tables, columns, fields, and query functions that the user has explicit access to.
+
+## Customizing Postgraphile
+
+By default, Postgraphile will expose queries for all tables defined in your chosen database/schema(s), including [filtering](https://www.graphile.org/postgraphile/filtering/) and [auto-discovered relations](https://www.graphile.org/postgraphile/relations/).
+
+If you'd like to expose more customized windows into your data, there are some techniques you can apply when writing migrations:
+
+- [Computed columns](https://www.graphile.org/postgraphile/computed-columns/) enable you to derive additional fields from types defined in your database.
+For example, you could write a function to expose a block header's state root over Postgraphile with a computed column - without modifying the `public.headers` table.
+- [Custom queries](https://www.graphile.org/postgraphile/custom-queries/) enable you to provide on-demand access to more complex data (e.g. the product of joining and filtering several tables' data based on a passed argument).
+For example, you could write a custom query to get the block timestamp for every transaction originating from a given address.
+- [Subscriptions](https://www.graphile.org/postgraphile/subscriptions/) enable you to publish data as it is coming into your database.
+
+The above list is not exhaustive - please see the Postgraphile documentation for a more comprehensive and up-to-date description of available features.
