+## Pack Formatter
+To use this, you must have the [Bun runtime](https://bun.sh) installed. Simply run `bun install`, `bun compile`, and you'll find the `build-packs` binary in the `dist` folder.
+
+## Usage
+```sh
+build-packs
+```
+
+### Arguments
+* `-i` or `--indir` - The input directory. Defaults to the current working directory.
+* `-o` or `--outdir` - The directory to output the compiled packs to. Defaults to dist.
+* `-c` or `--common` - The common directory containing shared files. Defailts to common.
+* `-r` or `--revision` - The revision/version. Defaults to `git rev-parse --short HEAD` if .git exists, else required.
