How-to-collaborate-on-github - A mini book about collaborating on GitHub

A much overlooked part of software making is how we choose to organize. How we can share the amount of work evenly and keep team-mates and contributors motivated. These are some of my observations on how we can organize better on GitHub. Prefer asynchronous collaboration over synchronous. As work becomes ever more complex and deep. Humans need less shallow focus and that means less interruption. Github handles this quite elegant through issues. Where one has to take extra care and be succinct in both asking and answering. Github recently also added edit history so one can investigate original issue and solution proposals which encourage even more diligence and less wasted mental bandwidth.
