The README file should also refer to
https://github.com/CommittedTeam/commitcanvas-models and explain that this
repository also includes details about the experiments conducted with
CommitCanvas, the results of those experiments, the details about the training
pipeline, and the instructions for downloading and using trained models. This
type of information will be valuable to researchers who want to extend the tool
or replicate an experimental analysis of CommitCanvas.
