+[![progress-banner](https://backend.codecrafters.io/progress/redis/f0888919-26c3-46fb-9854-4f2e891af515)](https://app.codecrafters.io/users/codecrafters-bot?r=2qF)
+
+This is a starting point for C++ 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 try the challenge.
+
+# Passing the first stage
+
+The entry point for your Redis implementation is in `src/Server.cpp`. Study and
+uncomment the relevant code, and push your changes to pass the first stage:
+
+```sh
+git commit -am "pass 1st stage" # any msg
+git push origin master
+```
+
+That's all!
+
+# Stage 2 & beyond
+
+Note: This section is for stages 2 and beyond.
+
+1. Ensure you have `cmake` installed locally
+1. Run `./your_program.sh` to run your Redis server, which is implemented in
+   `src/Server.cpp`.
+1. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
