 ## Features
 - Simple to use subcommands
-- Can install binary packages (and source packages in the future)
+- Can install binary and source packages
+- Can be easily installed on practically any system
+- No bloat
 
 ## Information
-BPM is still in very early development. Do not install it without knowing what you are doing. I would only recommend using it in a Virtual Machine for testing
+
+BPM is still in very early development. It should not be installed on any system you use seriously. I recommend trying this out in a VM or container. In addition to this, this is one of the first projects I have made using the go programming language so code quality may not be the best. This project was made to help me learn go and how linux systems work better. It is not meant to replace the big package managers in any way
 
 ## Build from source
 
 - Download `go` from your package manager or from the go website
 - Download `make` from your package manager
-- Download `which` from your package manager
+- Run the following command to compile the project
-- Run the following command to compile the project. You may need to set the `GO` environment variable if your Go installation is not in your PATH

 You can remove an installed package by typing the following

+The -y flag applies here as well if you wish to skip the removal confirmation prompt
-To remove all unused dependencies try using the cleanup command
-```sh
-bpm cleanup

-If using repositories, all packages can be updated using this simple command
-```sh
-bpm update

 For information on the rest of the commands simply use the help command or pass in no arguments at all
