Clarify license?

[gerritholl]

There is no license indicated for this repository. It would be good to clarify the license for the text, images, and (limited) code contained in this repository.

Recommendations as to which license to pick?

[gerritholl]

I think either CC-BY 4.0 or CC-BY-SA 4.0.

I think all co-authors to this repository (Adam, Martin, Dave, Panu, me) would need to agree. I don't know how this works for dependabot contributions.

A quick google makes me think the -SA portion isn't needed (require a similar license). At least right now this documentation/site is just informative and more of a convenience that would be annoying to find otherwise (packages, community info, etc). The only other thing that I'm not sure about would be the workshop info and pictures. It would be awkward to require conference presentations that use the workshop information from the website to have the CC-BY-SA license too.
