Improve guide on how to set the projects up

Make it easier to set up, add a guide. Combine API + bot so it's easier to host.

I'm currently working on utilising Docker to be able to deploy the applications and their necessary dependencies very easily.

If all that's working I'll update the README.md by:

• updating the current documentation on how to set it up.
• add a guide on how to deploy the applications using Docker.

On another note, I think merging both the bot and the API together into one repository is not something desirable.
It's like the client-server model, where the Discord bot (and group centers on Roblox) act as the client and the API as the server.
I also think merging both the quite big codebases together will result in a big mess :)
