+running the local backend with ``npm run backend:dev`` will create a new ``test.h2.db`` database in the tomcat root.
+
+if you start the local backend outside of an existing tomcat instance, you should also set the ``georchestra.datadir``
+property in the ``properties`` `section of web/pom.xml <https://github.com/georchestra/mapstore2-georchestra/blob/master/web/pom.xml#L20>`_, pointing at the full path of your local datadir.
