+If you want to make some template customization without building a brand new
+template, you should use this directory to store yur customized version of the
+official template files rather than editing them on place.
+Doing this, they won't be lost during the next upgrade.
+
+For example, if you want your own header file just copy 
+"template/yoga/header.tpl" to this directory with whatever, but significant,
+filename you want.
+Then edit "include/page_header.php" and replace the line :
+  $template->set_filenames(array('header'=>'header.tpl'));
+by
+  $template->set_filenames(array('header'=>'../../template-extension/yoga/local/header.tpl'));
+Or whatever new filename you gave instead of header.tpl
+
+In future version of PWG, you probably won't have to edit the php code, but
+a parameter table instead.
