Hi, I started installing ROS on my Slackware Linux system and got a error that my system is not recognized. ROS does not know anything about slackware at this point so I started manually tracking the points where rosdep fails. However, this manual tracking takes a lot of time and the moment I fix one error I get to the next one on the pipeline. I am currently quite ahead into the process but where can I read about the official requirements (if they exist) for adding support to new OS so I can implement them and later submit a pull request so my changes are added to the official packages?
