+![progress-banner](https://codecrafters.io/landing/images/default_progress_banners/interpreter.png)
+
+This is a starting point for C++ solutions to the
+["Build your own Interpreter" Challenge](https://app.codecrafters.io/courses/interpreter/overview).
+
+This challenge follows the book
+[Crafting Interpreters](https://craftinginterpreters.com/) by Robert Nystrom.
+
+In this challenge you'll build an interpreter for
+[Lox](https://craftinginterpreters.com/the-lox-language.html), a simple
+scripting language. Along the way, you'll learn about tokenization, ASTs,
+tree-walk interpreters and more.
+
+Before starting this challenge, make sure you've read the "Welcome" part of the
+book that contains these chapters:
+
+- [Introduction](https://craftinginterpreters.com/introduction.html) (chapter 1)
+- [A Map of the Territory](https://craftinginterpreters.com/a-map-of-the-territory.html)
+  (chapter 2)
+- [The Lox Language](https://craftinginterpreters.com/the-lox-language.html)
+  (chapter 3)
+
+These chapters don't involve writing code, so they won't be covered in this
+challenge. This challenge will start from chapter 4,
+[Scanning](https://craftinginterpreters.com/scanning.html).
+
+**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 program is in `src/main.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
+```
+
+Time to move on to the next stage!
+
+# Stage 2 & beyond
+
+Note: This section is for stages 2 and beyond.
+
+1. Ensure you have `cmake` installed locally
+2. Run `./your_program.sh` to run your program, which is implemented in
+   `src/main.cpp`.
+3. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
