so, first you'll need a faunadb database.
once you make an account, click "new database" and for the database name, whatever is fine.
then you'll need to make a collection. once in your db dashboard, click collections > new collection.
fill in the collection name (urls) and click save.
next, you'll have to make an index. same thing, in your db dashboard click indexes > new index.
call your index urls_by_key and under terms, enter data.key and under values enter data.value and ref.
next, go to the security tab and click new key. click save, then copy the key it gives you and save it somewhere important.
rename env.example to .env and fill in your db_key (created in the last step) and your auth key (whatever is fine).
now you can deploy!
install the vercel cli and do vc in whatever shell you use.
