## Usage ## Usage
```sh ```sh
./CHUNITHM-Patch-Finder <PATH TO EXE> ./CHUNITHM-Patch-Finder <PATH TO EXE> [PATH TO PATTERNS]
``` ```
The program expects a file called `patterns.yaml` (see files in If a patterns file is not specified, the program defaults to
repo for example) and outputs BemaniPatcher-compatible patches finding a file named `[file].yaml` under its `Patterns`
to `patches.json`. directory.
The output is in a format compatible with [BemaniPatcher](https://github.com/mon/BemaniPatcher).
