# `Resources` {#extension-resources}

Contains the sub folders `Public/` and `Private/`, which
contain resources, possibly in further subfolders.

Only files in the folder `Public/` should be publicly accessible.
All resources that only get accessed by the web server
(templates, language files, etc.) go to the folder `Private/`.
