+Custom modules can either be installed via package or git repository.
+Therefore set the variable `source` with either `package` or a string consisting `git,repository_url,tag/version/branch` 
+If no `tag/version/branch` is set the default `HEAD` will be used.
+
+Furthermore it's possible to differentiate between your own custom modules (for example custom themes) and Icinga specific modules.
+
+If you want to manage the config by yourself or the module doesn't need further configuration set the variable `manage_config` to `true` otherwise it needs to be set to `false`
+
+Example:
+```
+icingaweb2_modules:
+  my_theme:
+    enabled: true
+    manage_config: true
+    source: git,https://github.com/slalomsk8er/icingaweb2-theme-solarized.git,v1.0.0
