+This is a starting point for TypeScript solutions to the
+["Build Your Own grep" Challenge](https://app.codecrafters.io/courses/grep/overview).
+
+[Regular expressions](https://en.wikipedia.org/wiki/Regular_expression)
+(Regexes, for short) are patterns used to match character combinations in
+strings. [`grep`](https://en.wikipedia.org/wiki/Grep) is a CLI tool for
+searching using Regexes.
+
+In this challenge you'll build your own implementation of `grep`. Along the way
+we'll learn about Regex syntax, how parsers/lexers work, and how regular
+expressions are evaluated.
+
+**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 `grep` implementation is in `app/main.ts`. Study and
+uncomment the relevant code, and push your changes to pass the first stage:
+
+```sh
+git add .
+git commit -m "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 `bun (1.1)` installed locally
+1. Run `./your_grep.sh` to run your program, which is implemented in
+   `app/main.ts`.
+1. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
