Sometimes, we just need a little help from our friends. TNG does have help available and it is built into your edit and administration pages. For people able to log in and to edit the pages, help is found up near the tabs along the top of the page. Look for the “Help for this area” tag.

The pop-up window will have an excellent overview and instructions to guide you through the process. There will be several sections, depending on the function being described. Have a read through the whole help box for a full understanding.
