If you write "Template:Moveset" into the URL, past "/wiki/", you'll be moved to the Moveset page, where you can edit it. For other templates just replace "Moveset" with whatever the template name is.

As for how to make it work, it's mainly down to trial and error. I generally try to look for patterns, then just mess around a bit and see if it works. You can use preview to check, and if it doesn't work, just go back to the start and test changing something else.
