How to customise theme
This charm supports providing static source files for customising Indico look and feel. Indico’s official documentation contains more details on the contents of those files.
If you wish to apply a set of customisation files, set the configuration option customization_sources_url to the URL of the git repository containing them juju config [charm_name] customization_sources_url=[value]. If you want the favicon to be customised too, publish it as files/favicon.ico in the customisation repository. For debugging purposes, you may also want to enable customization_debug to get meaningful log messages when the files are accessed.
The theme changes can be pulled by running the refresh-external-resources action.
For more details on the configuration options and their default values see the configuration reference.
