Add a License File

[MiWeiss]

It appears that this repository does not have a license, which may disallow anyone to use its content (read about this here). Thus, would you mind adding a 'LICENSE' file to your repository?

By the way: To choose a license, choosealicense.com and the opensource guide are great places to start looking.
Adding the license to the repo can then easily be done using one of githubs template, as shown here.

Thanks in advance!
