What are Software Documentation Tools?

Software documentation tools are designed to help developers and technical writers create, manage, and share documentation related to software applications. These tools facilitate the writing of user guides, API references, installation instructions, and other types of technical content. They often include features like version control, templates, collaborative editing, and integration with code repositories to streamline the documentation process. Some popular tools offer support for various output formats, such as HTML, PDF, and Markdown, making it easier to distribute documentation to different audiences.
