+Documentation Style
+===================
+
+Documentation is crucial for the U-Boot project. It has to encompass the needs
+of different reader groups from first time users to developers and maintainers.
+This requires different types of documentation like tutorials, how-to-guides,
+explanatory texts, and reference.
+
+We want to be able to generate documentation in different target formats. We
+therefore use `Sphinx <https://www.sphinx-doc.org>`_ for the generation of
+documents from reStructured text.
+
+We apply the following rules:
+
+* Documentation files are located in *doc/* or its sub-directories.
+* Each documentation file is added to an index page to allow navigation
+  to the document.
+* For documentation we use reStructured text conforming to the requirements
+  of `Sphinx <https://www.sphinx-doc.org>`_.
+* For documentation within code we follow the Linux kernel guide
+  `Writing kernel-doc comments <https://docs.kernel.org/doc-guide/kernel-doc.html>`_.
+* We try to stick to 80 columns per line in documents.
+* For tables we prefer simple tables over grid tables. We avoid list tables
+  as they make the reStructured text documents hard to read.
+* Before submitting documentation patches we build the HTML documentation and
+  fix all warnings. The build process is described in
+  :doc:`/build/documentation`.
