Overriding the template files

To do deeper customization of your /friends/ page, you can override each of the templates by adding a file with the same name to your theme under a friends/ subdirectory.

So, for example to display Hello instead of the logged in /friends/ page, you’d create a file containing Hello in the friends/frontend/index.php file.

Since this is not very useful, you’d be best off by copying the respective file from the templates directory and then start your customization from there.
