License

I am also a big fan of explainshell. This looks like a useful tool. CC BY-NC-SA is not a license for code and is not a free culture license. Here is a link on the subject:

https://opensource.stackexchange.com/questions/1717/why-is-cc-by-sa-discouraged-for-code

I would suggest AGPL3.0 or MIT. The traditional github way of licensing is to add a LICENSE.md file. Github helps at that point with a pull down box with most of the common, free-culture licenses available.
