+This is a starting point for Haskell solutions to the
+["Build Your Own Redis" Challenge](https://codecrafters.io/challenges/redis).
+
+In this challenge, you'll build a toy Redis clone that's capable of handling
+basic commands like `PING`, `SET` and `GET`. Along the way we'll learn about
+event loops, the Redis protocol and more.
+
+**Note**: If you're viewing this repo on GitHub, head over to
+[codecrafters.io](https://codecrafters.io) to signup for early access.
+
+# Usage
+
+1. Ensure you have `stack` installed locally
+1. Run `./spawn_redis_server.sh` to run your Redis server, which is implemented
+   in `Main.hs`.
+1. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
+
+# Passing the first stage
+
+CodeCrafters runs tests when you do a `git push`. Make an empty commit and push
+your solution to see the first stage fail.
+
+```sh
+git commit --allow-empty -m "Running tests"
+git push origin master
+```
+
+You should see a failure message that says it wasn't able to connect to port
+`6379`.
+
+Go to `Main.hs` and uncomment the server implementation. Commit and push your
+changes, and you'll now see the first stage pass.
+
+Time to move on to the next stage!
