+# Lotus Command Line Interface
+
+The Command Line Interface (CLI) is a convenient way to interact with
+a Lotus node. You can use the CLI to operate your node,
+get information about the blockchain,
+manage your accounts and transfer funds,
+create storage deals, and much more! 
+
+The CLI is intended to be self-documenting, so when in doubt, simply add `--help`
+to whatever command you're trying to run! This will also display all of the 
+input parameters that can be provided to a command.
+
+We highlight some of the commonly
+used features of the CLI below.
+All CLI commands should be run from the home directory of the Lotus project.
+
+## Operating a Lotus node
+
+### Starting up a node
+
+```sh
+lotus daemon
+```
+This command will start up your Lotus node, with its API port open at 1234. 
+You can pass `--api=<number>` to use a different port.
+
+### Checking your sync progress
+
+```sh
+lotus sync status
+```
+This command will print your current tipset height under `Height`, and the target tipset height
+under `Taregt`. 
+
+You can also run `lotus sync wait` to get constant updates on your sync progress.
+
+### Getting the head tipset
+
+```sh
+lotus chain head
+```
+
+### Control the logging level
+
+```sh
+lotus log set-level
+```
+This command can be used to toggle the logging levels of the different
+systems of a Lotus node. In decreasing order
+of logging detail, the levels are `debug`, `info`, `warn`, and `error`. 
+
+As an example,
+to set the `chain` and `blocksync` to log at the `debug` level, run 
+`lotus log set-level --system chain --system blocksync debug`. 
+
+To see the various logging system, run `lotus log list`.
+
+### Find out what version of Lotus you're running
+
+```sh
+lotus version
+```
+
+## Managing your accounts
+
+### Listing accounts in your wallet
+
+```sh
+lo*tus wallet list
+``` 
+
+### Creating a new account
+
+```sh
+lotus wallet new bls
+```
+This command will create a new BLS account in your wallet; these
+addresses start with the prefix `t3`. Running `lotus wallet new secp256k1` 
+(or just `lotus wallet new`) will create
+a new Secp256k1 account, which begins with the prefix `t1`.
+
+### Getting an account's balance
+
+```sh
+lotus wallet balance <address>
+``` 
+
+### Transferring funds 
+
+```sh
+lotus send --source=<source address> <destination address> <amount>
+``` 
+This command will transfer `amount` (in attoFIL) from `source address` to `destination address`.
+
+### Importing an account into your wallet
+
+```sh

+# Frequently Asked Questions
+
+Here are some FAQs concerning the Lotus implementation and participation in 
+Testnet.
+For questions concerning the broader Filecoin project, please 
+go [here](https://filecoin.io/faqs/).
+
+## Introduction to Lotus
+
+### What is Lotus?
+
+Lotus is an implementation of the **Filecoin Distributed Storage Network**, written in Go. 
+It is designed to be modular and interoperable with any other implementation of the Filecoin Protocol.
+More information about Lotus can be found [here](https://lotu.sh/).
+
+### What are the components of Lotus?
+
+Lotus is composed of two separate pieces that can talk to each other:
+
+The Lotus Node can sync the blockchain, validating all blocks, transfers, and deals
+along the way. It can also facilitate the creation of new storage deals. If you are not 
+interested in providing your own storage to the network, and do not want to produce blocks
+yourself, then the Lotus Node is all you need!
+
+The Lotus Storage Miner does everything you need for the registration of storage, and the
+production of new blocks. The Lotus Storage Miner communicates with the network
+by talking to a Lotus Node over the JSON-RPC API.
+
+## Setting up a Lotus Node
+
+### How do I set up a Lotus Node?
+
+Follow the instructions found [here](https://docs.lotu.sh/en+getting-started).
+
+### Where can I get the latest version of Lotus?
+
+Download the binary tagged as the `Latest Release` from the
+ [Lotus Github repo](https://github.com/filecoin-project/lotus/releases).
+ 
+### What operating systems can Lotus run on?
+
+Lotus can build and run on most Linux and MacOS systems with at least 
+8GB of RAM. Windows is not yet supported.
+
+### How can I update to the latest version of Lotus?
+
+To update Lotus, follow the instructions [here](https://lotu.sh/en+updating-lotus).
+
+### How do I prepare a fresh installation of Lotus?
+
+Stop the Lotus daemon, and delete all related files, including sealed and chain data by 
+running `rm ~/.lotus ~/.lotusstorage`.
+
+Then, install Lotus afresh by following the instructions 
+found [here](https://docs.lotu.sh/en+getting-started).
+
+## Interacting with a Lotus Node
+
+### How can I communicate with a Lotus Node?
+
+Lotus Nodes have a command-line interface, as well as a JSON-RPC API.
+
+### What are the commands I can send using the command-line interface? 
+
+The command-line interface is self-documenting, try running `lotus --help` from the `lotus` home 
+directory for more.
+
+### How can I send a request over the JSON-RPC API?
+
+Information on how to send a `cURL` request to the JSON-RPC API can be found
+[here](https://lotu.sh/en+api). A JavaScript client is under development.
+
+### What are the requests I can send over the JSON-RPC API?
+
+Please have a look at the 
+[source code](https://github.com/filecoin-project/lotus/blob/master/api/api_common.go) 
+for a list of methods supported by the JSON-RPC API.
+## The Test Network
+
+### What is Testnet?
+
+Testnet is a live network of Lotus Nodes run by the 
+community for testing purposes.
+ It has 2 PiB of storage (and growing!) dedicated to it.
+
+### Is FIL on the Testnet worth anything?
+
+Nothing at all! Real-world incentives may be provided in a future phase of Testnet, but this is 
+yet to be confirmed.
+
+### Will there be future phases of Testnet?
+
+Yes, there will be at least one more phase of Testnet. We plan on introducing interoperable
+[go-filecoin nodes](https://github.com/filecoin-project/go-filecoin#filecoin-go-filecoin)
+in a future phase.
+
+### How can I see the status of Testnet?
+
+The [dashboard](https://stats.testnet.filecoin.io/) displays the status of the network as 
+well as a ton
+of other metrics you might find interesting.
+
+## Mining with a Lotus Node on Testnet
+
+### How do I get started mining with Lotus?
+
+Follow the instructions found [here](https://lotu.sh/en+mining).
+
+### What are the minimum hardware requirements?
+
+An example test configuration, and minimum hardware requirements can be found 
+[here](https://lotu.sh/en+hardware-mining). 
+
+Note that these might NOT be the minimum requirements for mining on Mainnet.
+
+### What are some GPUs that have been tested?
+
+A list of benchmarked GPUs can be found [here](https://lotu.sh/en+hardware-mining#benchmarked-gpus-7393).
+
+## Advanced questions
+
+### Is there a Docker image for lotus?
+
+Community-contributed Docker and Docker Compose examples are available 
+[here](https://github.com/filecoin-project/lotus/tree/master/tools/dockers/docker-examples).
+
+### How can I run two miners on the same machine?
+
+You can do so by changing the storage path variable for the second miner, e.g.,
+`LOTUS_STORAGE_PATH=~/.lotusstorage2`. You will also need to make sure that no ports collide.
+
+### How do I setup my own local devnet?     
+
+Follow the instructions found [here](https://lotu.sh/en+setup-local-dev-net).
