As stated earlier on module can be used to link or group a set of resources together. These resources are referred to as module dependencies.
Note The Dependencies tab is only available when editing the module. It is not available when creating a new module.
From the Dependencies tab you can click the "Manage dependencies" button to add and remove resources:
You can use the "Remove" button to remove selected resources while the add buttons will allow you to add new resources.
Before a snippet or plugin can access a modules shared parameters it must be added to the module's dependencies list.
