Learning links for the new contributor to `serverless-concept`

Thinking we'll have to update the README with some links to get a new contributor unfamiliar with GraphQL and Apollo Client acclimated.

Feel free to paste links below.

One that @d3vild06 shared on Slack, which I'm reading through right now: https://www.apollographql.com/docs/tutorial/introduction/

FaunaDB tutorial: https://github.com/netlify/netlify-faunadb-example

One thing I'm still slightly confused about is how we'd set up a local FaunaDB instance whose data would differ from what's in production. Or would the local DB automatically... be there, as we're writing the POST functions?

That tutorial above also looks like it's not making use of GraphQL/Apollo Client, so our code would look different, if I'm reading it right.
