+# What problem does it solve?
+
+I have a few php based projects with or without a database.
+
+As a newbie in docker I installed a rootless docker.
+
+And to dockerfy exsiting projects quick and dirty. Sure copy & paste works, but if you have multiple configuration files where variables must match then variables are very helpful. So here is a stupid simple template generator.
+
+The init script:
+
+* sets permisssions for container and local user
+* generates needed files for docker from configuration and a set of templates
+* starts/ stops your container
+
+# What problems does it not solve?
+
+It is a script for a dual container and Apache + PHP and Mariadb only. Nothing else.
