Opensource documentation?

I would love to share my experience with Mozilla webthings and gateway in a documentation somehow. I think I can add a touch of unskilled documentation level so People like me, that just try to make something with little knowledge, are able to hack a webthing without the headache.
Does there exist some way to let me contribute to any of the Documentation sources?

We have some general documentation available here, which is publicly editable: https://github.com/mozilla-iot/wiki/wiki

If you’d like to add something to the webthing Python library itself, you can open a pull request to this repo.
