The Home Screen and the About Screen needs new documentation! It is important that this is implemented because it helps users understand that page better and allows them to hop into implementation sooner.

Requirements: What needs to be written in the docusaurus is this

1. Introduction
2. Description of each component
3. Packages in the code
4. How it was implemented
5. Possible improvements
6. Any known bugs
