p.s. it would be great to add #hacktoberfest topic to the project

[piggz]

Youll have to explain to me what adding #hacktoberfest will do :)

[jmlich]

There is an web site about that https://hacktoberfest.com/

Basically, every merged merge request counts to competition. After 3 accepted merge requests I will get an reward. This year the reward is planted tree in my name.

Sounds like a good enough reason!
