+## Windows Subsystem for Linux
+
+Follow the steps below to set up rodo on GNU/Linux
+
+### Set up a $PATH
+
+1. Create a directory for your `$PATH` by running `mkdir ~/bin/`
+2. Add your newly-created `~/bin/` to your `$PATH` by running `echo "export PATH=~/bin:\$PATH" >> .bashrc`
+
+### Adding rodo to your $PATH
+
+1. Create a file in your `~/bin/` directory with the following contents in it:
+
+```
+#!/usr/bin/env bash
+racket ~/path/to/rodo.rkt "$@"
+```
+
+For example, if you downloaded the project to your
+`~/downloads/` folder you would change the line `racket
+~/path/to/rodo.rkt "$@"` to `racket
+~/downloads/rodo/rodo.rkt "$@"`.
+
+If you prefer to use an executable, rather than a wrapper,
+you can create an executable binary file with `raco exe
+file-name-here.rkt`.
+
+2. Save the file
+
+3. Make the file executable by running `chmod u+x ~/bin/name-of-your-file`
