 Theming
 =======
 
-Nextcloud has two ways of theming. There is a theming app that provides a web
-UI to set up theming. The second option allows to overwrite most of the files
-but a customized theme needs to be created and maintained. For more information on
-this check out the `developers documentation <../../developer_manual/core/theming.html>`_.
+With our theming feature you are able to customize the look and feel of your
+Nextcloud instance according to the corporate design of your organization by
+replacing Nextcloud logo and color with your own assets.
 
-We recommend to use the theming app, because the Nextcloud team maintains this
-and verifies that all adjustments to the server work with the theming. It
-covers also most use cases like replacing the name, logos and colors.
+.. note:: Nextcloud also provides an more advanced but unmaintained theming which
+   allows you to overwrite most of the servers code. For more information on
+   this check out the `developers documentation <../../developer_manual/core/theming.html>`_.

 Theming of icons
 ----------------
 
-Nextcloud will automatically generate favicons and home screen icons
-depending on the current app and theming color. 
+According to the parameters you have set, Nextcloud will automatically generate
+favicons and a header logo depending on the current logo and theming color.
 
 This requires the following additional dependencies:
 
- - PHP module imagick
- - SVG support for imagick (e.g. `libmagickcore5-extra`)
+ - PHP module ``imagick``
+ - SVG support for imagick (e.g. ``libmagickcore5-extra``)
 
-Theming of mobile app URLs and IDs
-----------------------------------
+.. note:: In the advanced options of the theming-app you are able to set a custom
+   header logo and Favicon in case you do not want to use the same logo resources
+   you have set above or you do not want to install the mentioned dependencies.

+The theming-app supports to change the URLs to the mobile apps (Android & iOS) that
+is shown when the webinterface is opened on one of those devices. Then there was a
 header shown, that redirects the user to the app in the app store. By default
 this redirects to the Nextcloud apps. In some cases it is wanted that this
 links to branded versions of those apps. In those cases the IDs and URLs can be
-set via the occ command::
