Documenting code on GitHub is crucial for project success, as accessible and readable documentation aids understanding and collaboration. Recent UI improvements to GitHub Wikis enhance the creation, editing, and interaction with wikis, aligning them more closely with other repository features and setting the stage for future updates. These enhancements include an improved sidebar that lists all wiki pages and allows for custom content, as well as consistent rendering of wiki content with other repository markup. Additional features such as emojis and task lists are now supported. For those new to wikis, GitHub provides a guide and showcases exemplary wikis for inspiration, along with updated documentation articles for further assistance.
