## Config File Discovery

The config file is a file named `.yamlfmt`, `yamlfmt.yaml`, or `yamlfmt.yml` that contains a valid yamlfmt configuration. The config file is discovered in the following priority order:
The config file is a file is a yaml file that contains a valid yamlfmt configuration. yamlfmt will automatically search for files with the following names:

- `.yamlfmt`
- `yamlfmt.yml`
- `yamlfmt.yaml`
- `.yamlfmt.yaml`
- `.yamlfmt.yml`

You can also pass a config file to yamlfmt using the `-conf` flag. When using the `-conf` flag, the config file can be named anything.
When not using one of the config file flags, it will be automatically discovered in the following priority order:

1. Specified in the `-conf` flag (if this is an invalid path or doesn't exist, the tool will fail)
1. A config file in the current working directory

If the flag `-global_conf` is passed, all other steps will be circumvented and the config file will be discovered from the system config directory. See [the command line flag docs](./command-usage.md#configuration-flags).

In the `-conf` flag, the config file will be named anything. As long as it's valid yaml, yamlfmt will read it as a config file. This can be useful for applying unique configs to different directories in a project. The automatic discovery paths do need to use one of the known names.
