 ## Local development
 
-Python dependencies are tied to the versions available in Debian.
+Python dependencies in `requirements.txt` are tied to the versions available in
+Debian:
 
     python3 -m pip install -r requirements.txt
-    cd www
+
+You'll need a copy of `conservancy/djangocommonsettings.py`, a file that not
+committed to the repository that has database settings and other
+environment-specific config.
+
+Then run:
+
+    python manage.py migrate
     python manage.py runserver
 
+There is also a Dockerfile available if that's more convenient. See that file
+for details.

 ## Deploying
 
 Changes pushed to the https://k.sfconservancy.org/website repository are
 automatically deployed to the production website by the `conservancy-www-update`
 SystemD timer. See `systemd/conservancy-www-update.timer` for details.
+
+The `migrate` and `collectstatic` commands are not run automatically. You may
+need to run these if modifying the database schema or adding/moving static files:
+
+    sudo -u www-data /var/www/venv-website/bin/python manage.py migrate
+    sudo -u www-data /var/www/venv-website/bin/python manage.py collectstatic --link
