+## Documentation versioning 
+The versioning documentation of Docusaurus can be found [here](https://docusaurus.io/docs/versioning).
+Specifically, a new version can be created with the following command: 
+```
+npm run docusaurus docs:version <versionName>
+```
+
+When tagging a new version, the document versioning mechanism will:
+
+* Copy the full `docs/` folder contents into a new `versioned_docs/version-<versionName>/` folder.
+* Create a versioned sidebars file based from your current sidebar configuration, saved as `versioned_sidebars/version-<versionName>-sidebars.json`.
+* Append the new version number to `versions.json`.
