How To Write Effective Documentation For Your Open Source Project

Unfortunately, good code won't speak for itself. Even the most elegantly designed and well-written codebase that solves the most pressing problem in the world won't just get adopted on its own. You, the open source creator, need to speak for your code and breathe life into your creation. That's where technical writing and documentation come in. A project's documentation gets the most amount of traffic, by far. It's the place where people decide whether to continue learning about your project or move on. Thus, spending time and energy on documentation and technical writing, focusing on the most important section, "Getting Started," will do wonders for your project's traction.
