GitHub Pages has become a favored tool for publishing and maintaining documentation due to its recent improvements, allowing users to easily create websites directly from their repository's /docs folder. This platform is particularly beneficial for open-source projects as it simplifies the process of sharing well-curated documentation, which is crucial for fostering collaboration and providing guidance. By integrating with Jekyll, GitHub Pages supports writing in plain text or Markdown and offers tools like variables and templates, thus retaining flexibility without the complexity of traditional web publishing. Importantly, it enables documentation to reside alongside the code on GitHub, facilitating the use of GitHub's collaborative features like Issues and Pull Requests. Setting up a GitHub Pages site is straightforward: users can create a /docs/index.md file, commit changes, adjust repository settings, and GitHub Pages will convert and publish the content, offering a streamlined approach to documentation management.
