Add docs for needed physical template file

[isellsoap]

I feel a bit stupid about this, but anyway:

I stumbled upon this and think that the docs should mention that you need to add a physical template file in the template files location of ProcessWire in order for receiving webmentions to work. I didn’t find anything about it (maybe because it’s too obvious).

Maybe the module could try to create the physical template file itself (if the server allows it with it file system permissions)?

Maybe it would also be a good idea to pre-fill the template (maybe also only adding a comment in the template file) that the visible webmention page in the frontend should have some content like your webmention endpoint), which I find quite good. Or at least explain what exactly is necessary to add such a form on the page.

Good ideas. I did include a basic template file for it in /extras but apparently forgot to update the readme with directions to copy it into the templates directory after install.

Ok, I overlooked that folder. Thanks! 👍
