+
+This is a starting point for Clojure solutions to the
+["Build Your Own HTTP server" Challenge](https://app.codecrafters.io/courses/http-server/overview).
+
+[HTTP](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) is the
+protocol that powers the web. In this challenge, you'll build a HTTP/1.1 server
+that is capable of serving multiple clients.
+
+Along the way you'll learn about TCP servers,
+[HTTP request syntax](https://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html),
+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 HTTP server implementation is in
+`src/http_server/core.clj`. 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
+```
+
+Time to move on to the next stage!
+
+# Stage 2 & beyond
+
+Note: This section is for stages 2 and beyond.
+
+1. Ensure you have `clj` installed locally
+1. Run `./your_program.sh` to run your program, which is implemented in
+   `src/http_server/core.clj`.
+1. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
