How To Add To The Wiki?

I wanted to add a couple guides to the wiki but couldn’t find a way to create a new page and then link it to the ‘Help and support’ section on the main page.

Any instructions on creating a new page, not editing an existing one?

PS:

The two guides I wanted to create were my ‘edit and continue’ guide and a guide on maintaining a remote patch repo for pull requests with TortoiseGIT.
