[💡 FEATURE] - Adding More Documentation

Adding extra documentation to this repo like mentioned [here](https://guides.github.com/features/wikis/) such as:

- SHORTCUTS.md: List of shortcuts and what they map to
- Creating a wiki section and redirecting users to that, maybe shortcuts can be on wiki as well
- Moving docs or intro to a github pages like [here](https://github.blog/2016-08-22-publish-your-project-documentation-with-github-pages/) and then move all relevant docs in a /docs folder
- Also moving some sections out of README into their own files as README getting bit big or just using a table of contents so easy to navigate README

Definitely a suggestion for when the project is more mature and has more stuff to document
