+Normal templates go in this directory. You can load them in your
+code like this:
+
+use B[% %]ugzilla::Error;
+my $template = B[% %]ugzilla->template;
+$template->process('[% name FILTER lower %]/some-template.html.tmpl')
+  or ThrowTemplateError($template->error());
+
+That would be how to load a file called some-template.html.tmpl that
+was in this directory.
+
+Note that you have to be careful that the full path of your template
+never conflicts with a template that exists in [% terms.Bugzilla %] or in 
+another extension, or your template might override that template. That's why
+we created this directory called '[% name FILTER lower %]' for you, so you
+can put your templates in here to help avoid conflicts.
