Grackle: Functional GraphQL for the Typelevel stack

How to Learn

There is a work-in-progress microsite which contains a tutorial walkthrough of the included demo project. This hasn't found a permanent home yet, and for now can most easily be accessed by running,

sbt docs/previewSite

and then browsing to localhost:4000.

How to Contribute

If you see a typo in the doc, click the link at the bottom and fix it!
If you find a bug, open an issue (or fix it and open a PR) at our GitHub Repository.
If you want to make a larger contribution please open an issue first so we can discuss.
