 ## Features
 - Simple to use subcommands
-- Can install binary and source packages
-- Can be easily installed on practically any system
-- No bloat
+- Can install binary packages (and source packages in the future)
 
 ## Information
-
-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
+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
 
 ## Build from source
 
 - Download `go` from your package manager or from the go website
 - Download `make` from your package manager
-- Run the following command to compile the project
-```
+- Download `which` from your package manager
+- 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
+```sh
 make
 ```
-- Run the following command to install stormfetch into your system. You may also append a DESTDIR variable at the end of this line if you wish to install in a different location

-You may also use the -y flag as shown below to bypass the installation confirmation prompt
+You can also use the package name directly if using databases
+```sh

+The -y flag may be used as shown below to bypass the confirmation prompt
 ```sh
 bpm install -y /path/to/package.bpm

+Flags must strictly be typed before the first package path or name, otherwise they'll be read as package locations themselves
 
 You can remove an installed package by typing the following
 ```sh
 bpm remove package_name
 ```
-The -y flag applies here as well if you wish to skip the removal confirmation prompt
+
+To remove all unused dependencies and clean cached files try using the cleanup command
+```sh
+bpm cleanup
+```
+
+If using databases, 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
-```
+```sh
 bpm help
 ```
