+# Activity Events MySQL store
+
+## Using MySQL for fresh installations
+
+To enable MySQL add to your management service the following environmental variable:
+```bash
+NB_ACTIVITY_EVENT_STORE_ENGINE=mysql
+NB_ACTIVITY_EVENT_MYSQL_DSN="mysql://<username>:<password>@<host>:<port>/<db_name>"
+```
+
+You can switch back to sqlite storage by setting the `NB_ACTIVITY_EVENT_STORE_ENGINE` variable to `sqlite`.
+<Note>
+    Switching between storage options requires migration steps to prevent data loss.
+</Note>
