 - go (1.13 or higher)
 - gcc (7.4.0 or higher)

+2. Clone this repo & `cd` into it
+```
+$ git clone https://github.com/filecoin-project/lotus.git

+3. Build and install the source code
 ```
 $ make

+Now, you should be able to perform the commands listed below.

 ### Node setup

 If you have run lotus before and want to remove all previous data: `rm -rf ~/.lotus ~/.lotusstorage`

-[You can copy `lotus` and `lotus-storage-miner` to your `$GOPATH/bin` or `$PATH`, or reference all lotus commands below from your local build directory with `./lotus`]

 The following sections describe how to use the lotus CLI. Alternately you can run lotus nodes and miners using the [Pond GUI](#pond).
