-=== Configuration ===
+To use the web interface, you need add a super user first. Further
+user can then be imported using the web interface. Creation of the
+initial super user is done with the following commands:
- * mv example.cfg ktt-shopsystem.cfg
- * edit ktt-shopsystem.cfg
+ * `busctl --system call io.mainframe.shopsystem.Database /io/mainframe/shopsystem/database io.mainframe.shopsystem.Database UserReplace "(issssssssxbbsas)" "<userid>" "<firstname>" "<lastname>" "<email>" "<gender>" "<street>" "<postcode>" "<city>" "" 0 0 0 "" 0`

-=== Database ===
+Unfortunately the web interface does not yet allow do add categories
+or suppliers. You can use the following queries to add this before
+adding products:
- * Create initial account with super user permissions
