+# Working on docs locally
+
+To work on documentation locally and preview it while developing, we can use `mkdocs serve`
+
+Start by installing the requirements for documentation.
+
+``` shell
+pip install -r doc-requirements.txt
+```
+
+!!! tip
+
+    You may want to first create a virtualenv and install requirements in there.
+
+Once the installation is done, run the mkdocs server locally to view your changes.
+
+``` shell
+cd genestack/
+mkdocs serve
+```
