-Real documentation coming soon, for now refer to the [original Matryoshka docs](https://github.com/slamdata/matryoshka/blob/master/README.md) for an explanation of the general concepts!
-A port of the example used in these docs is available [here](https://github.com/slamdata/purescript-matryoshka/blob/master/test/Test/Example/Expr.purs).
-A simple example showing the use of `cata`, `ana` and `hylo` is [here](https://github.com/slamdata/purescript-matryoshka/blob/master/test/Test/Example/List.purs).
+`matryoshka` documentation is stored in a few places:
+
+1. Module documentation is [published on Pursuit](https://pursuit.purescript.org/packages/purescript-matryoshka).
+2. Written documentation is kept in the [docs directory](./docs).
+3. Usage examples can be found in [the test suite](./test).

+
+- [Open an issue](https://github.com/purescript-contrib/purescript-matryoshka/issues) if you have encountered a bug or problem.
+- [Search or start a thread on the PureScript Discourse](https://discourse.purescript.org) if you have general questions. You can also ask questions in the `#purescript` and `#purescript-beginners` channels on the [Functional Programming Slack](https://functionalprogramming.slack.com) ([invite link](https://fpchat-invite.herokuapp.com/)).
