README.md changes

[ralphmchugh]

This is a non-urgent issue to make the README.md look super legit
Mostly it needs

1. What the api does ( since it doesn't actually do anything rn, not a big deal)
2. How to run the server locally and then how to call locahost and stuff
3. those cool tags I see at the top of other other repos
4. pretty emojis
   After we get it super legit looking, other stuff we can add:
   FAQ
   config
   screenshots
