+## Adding a new data source
+
+Adding a new data source is easy! To do so, in your fork or branch of the project, do the following:
+
+* Create a renku dataset using `renku dataset create [dataset name]`
+* Add any files or folders using `renku dataset add`. [Looking in the commit history will provide some examples](https://renkulab.io/gitlab/covid-19/covid-19-public-data/commits/master).
+* Create a notebook that shows how to read and work with the dataset in the `notebooks/examples` folder
+    * Protip: use a unique name for the notebook to avoid merge conflicts
+* Add an issue to the project for any suggestions on things to do with the data
