Do you want to be known in the open source world? If you don't, don't watch this video. If you do, there are eight things you should pay attention to when making a new GitHub repo: 1) make it small, 2) don't depend on other libraries, 3) make your README sexy, 4) write up a complete documentation, 5) ask everybody around to give you GitHub stars, 6) release it, 7) configure continuous integration, 8) communicate with your users via issues and pull requests. You can see how I do it in my libraries, in my GitHub account: https://github.com/yegor256
