Add documentation of how to set this up

[augbog]

Try to find time to add documentation on how to set this up on a Raspberry Pi. For people looking for immediate documentation, I have instructions in another Slack app I wrote.

Also the README tells you how to run it on your local machine but naturally people might not like it.

Hey! 👋 I opened a pull request to address this: #5. It adds comprehensive setup documentation, including instructions for the Raspberry Pi and better guidance for running it locally. Let me know what you think!
