 ### Add your own feature / matcher
 
-I provide an example to add local feature in [hloc/extractors/example.py](hloc/extractors/example.py). Then add feature settings in `confs` in file [hloc/extract_features.py](hloc/extract_features.py). Last step is adding some settings to `matcher_zoo` in file [common/config.yaml](common/config.yaml).
