You can find all BlackArch code (including build scripts and website source) on our github.
If you have any questions, suggestions, or bugs to report, feel free to post on the issue tracker. We also accept pull requests of all sizes and importance.
Come keep us company. We have a little community here. Anything is on topic but the large majority of discussion is related to security and/or BlackArch.
If you need help, this is the best place to ask.
We also have a little bot that notifies the channel of git commits and package updates/additions.
You can find the official BlackArch IRC channel here: #blackarch on Freenode
If you aren't familiar with the protocol IRC, use the webchat of Freenode. Just enter any nickname and the channel #blackarch (don't forget #) for join us now.
We have an on-site blog. The posts are usually more detailed than our Twitter posts and focus on more big project issues.
We also release interesting blog entries about BlackArch, hacking, and security written by users. If you wish to add a blog entry please open a pull request on Github.
