Software License Recommendation

[degregat]

I've seen some unlicensed research code being published, which makes reuse hard and increases friction. Usually that was not the intent, but a result from a lack of knowledge of the legal implications.

Would it make sense to add a section with a short explanation why adding a software license is important, as well as a recommendation? MIT and APACHE 2.0 seem to be favored and a short explanation of their mechanics could be included.

If that is something that is wanted, I can open a PR.
