+
+This is a starting point for Swift solutions to the
+["Build Your Own Git" Challenge](https://codecrafters.io/challenges/git).
+
+In this challenge, you'll build a small Git implementation that's capable of
+initializing a repository, creating commits and cloning a public repository.
+Along the way we'll learn about the `.git` directory, Git objects (blobs,
+commits, trees etc.), Git's transfer protocols 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 Git implementation is in `Sources/main.swift`. 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
+```
+
+That's all!
+
+# Stage 2 & beyond
+
+Note: This section is for stages 2 and beyond.
+
+1. Ensure you have `swift` installed locally
+1. Run `./your_git.sh` to run your Git implementation, which is implemented in
+   `Sources/main.swift`.
+1. Commit your changes and run `git push origin master` to submit your solution
+   to CodeCrafters. Test output will be streamed to your terminal.
+
+# Testing locally
+
+The `your_git.sh` script is expected to operate on the `.git` folder inside the
+current working directory. If you're running this inside the root of this
+repository, you might end up accidentally damaging your repository's `.git`
+folder.
+
+We suggest executing `your_git.sh` in a different folder when testing locally.
+For example:
+
+```sh
+mkdir -p /tmp/testing && cd /tmp/testing
+/path/to/your/repo/your_git.sh init
+```
+
+To make this easier to type out, you could add a
+[shell alias](https://shapeshed.com/unix-alias/):
+
+```sh
+alias mygit=/path/to/your/repo/your_git.sh
+
+mkdir -p /tmp/testing && cd /tmp/testing
+mygit init
+```
