Documentation Needed

[stjet]

• [x] Env documentation
• [x] Contributing / Testing process
• [x] How to fork
• [x] Project structure
• [x] CSS
• [ ] About Vercel and Svelte

Probably some more, feel free to suggest and I'll edit and add

Contributing docs should include code formatting standards, #188 might be related

There's a contribution guide at https://github.com/repldex/Repldex/blob/v3/CONTRIBUTING.md which also includes an overview of the code structure. It could definitely be improved though.
