There are several areas where you can help.


I’m not native English speaker and some of my sentences sound weird. Fork blackmamba repository, update documentation and open pull request. Will happily merge it.


If you find a bug, please do not hesitate to file an issue. I’m unable to test everything.


Do you have a question? File an issue, I’ll add question tag and will answer it. Or you can send me direct message on Twitter.

New ideas

I’m open to new ideas as well. Please, file an issue.
