+
+
+            This app will install a default postgres instance with persistant data. You can choose the version yourself. The deployment was tested with postgres 12.x.
+
+            After the installation we'll fork a slightly customized version of the original umami package which makes sure that your data is not corrupted on new container deployments or restarts. 
+            Open a PR on https://github.com/tschannik/caprover-umami of your desired umami-version is not supported.
