Forward

This will be the steps to setup my (very opinionated) shell environment. Many things may go wrong (environmental variables, paths, etc), but this could be a great learning opertunity.

Use the man command for help! Man pages are viewed in less, try man less to learn how to navigate them better!

Setup

Install Nix Package Manager
