I need document my python project using Sphinx. But I can't use autodoc. When I config my project I select the option "extension autodoc", but now if I use .. autoclass:: Class, I have a ERROR: ERROR: Unknown directive type "autoclass" I configure the PYTHONPATH, and now it's good. But I already have this problem. My index file is: .. ATOM documentation master file, created by sphinx-quickstart on Thu Nov 22 15:24:42 2012. You can adapt this file completely to your liking, but it should at least contain the root toctree directive. Welcome to ATOM's documentation! Contents: .. toctree:: :maxdepth: 2 .. automodule:: atom Indices and tables :ref:genindex :ref:modindex :ref:search Thank you, I need that someone say me how I find the problem, or how i can fix this! Sorry for my English, I start now to learn English.
