Should ipynb checkpoints be stored in Git?

As the title says: I'm checking a Jupyter notebook into a GitHub repo, should I store the .ipynb_checkpoints folder in GitHub too, or are they best .gitignored and kept locally?

I'm not really sure what they are for, so I don't know whether to include them or not.

The checkpoints are similar files as the original notebooks but are only updated on a manual save. The original notebooks are updated with autosave and when manually saving (thanks @Thomas K).

The question to you is if you want to share your manual saves with your collaborators. I prefer not to share those because git already provides the functionality to go back to an older version.

Also, I use https://www.gitignore.io/ to create .gitignore files and according to them the checkpoints are temporary data.
