+## Documentation
+
+Each directory contains a README.md with the basic information, examples and usage.
+It does not however contain API documentation, which is built separately in this directory.
+
+### Requirements
+
+The code is documented with [Doxygen][doxygen] JavaDoc style, a prettified documentation
+also requires [breathe][breathe] and [Sphinx][sphinx] for building sane documentation pages.
+It is not however required.
+
+[doxygen]:https://www.stack.nl/~dimitri/doxygen/manual/index.html

+You can get the extra dependencies with pip:
+
+```sh
+pip install -U Sphinx breathe
