A "How To" is a short page describing how to do something or achieve some goal from within the site.
Write a HowTo Wiki page whenever you think "wouldn't it be nice to have some documentation for that the thing I just did, so I don't have to remember
how to do it again".
Include the words
How to in the body of your page, and give the page a name with
HowTo in the title, that way we can run a script to create a table of contents of all our how tos.
