View source for Template Overrides

== Example: Template Override for mod_login == <!--T:4-->

<!--T:5-->
Start by selecting {{rarr|System,Templates,Site Templates}} in the Administrator menu and then select the Cassiopeia Details and Files item. That will open the Templates: Customise (Cassiopeia) form:

<!--T:6-->
[[File:J4x-templates-customise-cassiopeia-en.png|800px|center|Cassiopeia Files]]

<!--T:7-->
'''Important:''' do not edit any of the files supplied as part of the Cassiopeia template. At the next Joomla update those files may be overwritten and your edits will be lost.

<!--T:8-->
The html folder is where overrides are located. If you expand the html folder you will see that there are already overrides for layouts, mod_custom, mod_menu and tinymce. Expand each to see what is in them. There is no mod_login at this stage.
