Using hooks, you can insert blocks of code in many parts of the Back-office.

Doing this is very simple. You just have to create a html file (file name is important and depends on the hook) in your AdminIncludes folder and it will be parsed and included in the Back-office.

Your file must have the same name as the hook you want your markup to affect. For example, if the hook name is product-edit, my file name must be product-edit.html.

You can discover all available hooks if you put SHOW_INCLUDE=1 in your query string. This only work in debug mode.
