Effective collaboration across teams is crucial for the success of any project. GitHub offers a range of tools for technical documentation, including the ability to host GitHub Pages, Wikis, and tutorials directly from the platform. In addition, GitHub's READMEs are a valuable resource for sharing non-technical information about your organization, project, or repository that can be easily understood by everyone. Profile READMEs for individuals and organizations can also be used to showcase yourself and your organization to the community.
Storing all the necessary information together with your code ensures that everyone involved in the project can easily access it. This means that your documentation will receive the same level of attention as your code and can be integrated into the same workflow.
