 ## Project Information
 
+### Background
+
+`crowsetta` was developed for two libraries:
+- `hybrid-vocal-classifier` <https://github.com/NickleDave/hybrid-vocal-classifier>
+- `vak` <https://github.com/NickleDave/vak>
+
+Testing relies on the `Vocalization Annotation Formats Dataset` which you may find useful if you need
+small samples of different audio files and associated annotation formats
