reStructuredText
reStructuredText is a lightweight markup language used primarily for creating technical documentation, especially in Python projects. It provides a simple, readable syntax for writing structured documents that can be easily converted to formats like HTML, PDF, and LaTeX. It is the default markup language for Python's Sphinx documentation generator.
Developers should learn reStructuredText when working on Python projects that require comprehensive documentation, as it integrates seamlessly with Sphinx and tools like Read the Docs. It is ideal for creating API documentation, user manuals, and project wikis due to its support for cross-references, tables, and code blocks. Use it in environments where maintainable, version-controlled documentation is essential, such as open-source software or enterprise applications.
