The text below is displayed on every booster template page in order to show the effects of edits. (Template loop errors will disappear there.)
Template loop detected: Template:Documentation
This documentation is automatically generated for all booster templates. It shows the effects of your edits on the different display styles.
Note: Previewing or publishing the page does not display your edits. You have to click the purge link at the top of this documentation. This will force the server to clear the cache of the page, parse it again and show the changes.
