 Mash is a shell (like sh, bash, fish, or zsh) which has been coded in Python by me. At the moment, Mash is still in a very early alpha stage. (As in it "works", but there's no guarantee that it *will* work.) There's a few built in commands (mls for ls, and mat for cat) to allow for higher consistency across different systems, but these are very basic (just use your system-bundled versions kind of basic). 
 
 ## Features

 * Coded in Python, meaning you can quickly make a change to the code in real time
 * Colourful out of the box

 **However, Windows support is very hit and miss. Don't see this as a Powershell replacement.** Yes, I know Powershell and the regular Command Prompt suck, but for now don't expect good support. Running programs is tested and working, however using directories gets a bit messy due to the differences between UNIX-like and NT design.
 
+## Setup
+
+If you decide for whatever reason you would like to use Mash, here's some steps:
+
+1. Clone the repo
+
+2. Create the files .history.mash and .config/mash/mash.conf
+
+3. Make sure `colorama` is installed, as this is what currently provides the colours for Mash.
+
+4. Run main.py

 ## Configuration (EARLY BETA)
 
 Mash is a "configurable" shell. You can customise some parts of it to make it your own. It uses a syntax that is sort of inspired by CSS (emphasis on the sort of), but I just coded whatever felt easiest to code.
