+## Reviewing Jupyter notebooks with ReviewNB
+For rich diffs and commenting on Jupyter notebooks Github is not very useful, because Github shows differences between Jupyter notebooks as a diff between json files.
+You can use [ReviewNB](https://www.reviewnb.com/) for reviewing Jupyter notebooks. ReviewNB shows the diff between notebooks in a human readable way.
+ If you configure
+your esciencecenter.nl email address as your primary email for your Github
+account [here](https://github.com/settings/emails) you have access to the 
+academic plan with full benefits.
