looks awesome, giving it a try!

Just got a custom monirail function up and running (without Docker), really cool! Just wanted to say thanks for building this

Could potentially improve the docs a little for users who wish to setup their own custom functions? Or perhaps I overlooked the docs for doing this?

Couple of little snags I hit:

• A railway.yaml example could be nice, with the correct settings for the Railway function and it's volume - I only realised a volume was required when I hit the SQLiteError: unable to open database file error.

• Also, I know it's silly, but I got tripped up on which type of token to use. Accidentally used a User API TokenRAILWAY_TOKEN (e.g. Account → Tokens) instead of Project/Service tokenRAILWAY_API_TOKEN (e.g. Project → Settings → Tokens) - didn't take too long to figure this out, but all these little things just added friction to getting up and running.
