+# 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
+lotus wallet import <path to private key>
+``` 
+This command will import an account whose private key is saved at the specified file.
+
+### Exporting an account from your wallet
+
+```sh
+lotus wallet export <address>
+``` 
+This command will print out the private key of the specified address
+if it is in your wallet. Always be careful with your private key!
