 The documentation is built using [Doxygen](http://www.stack.nl/~dimitri/doxygen/), [Breathe](https://breathe.readthedocs.io/en/latest/) and [Sphinx](http://www.sphinx-doc.org/en/stable/). Install Doxygen and Python (2 or 3) and make sure they're accessible from your `PATH`, then run:
 
 ```
-pip install -r docs/api/requirements.txt
+pip install -r docs/requirements.txt
 sphinx-build -b html docs build/docs/html
