This installs Sphinx +in a container, adds the local ``docs/`` directory and builds the HTML +docs inside the container, even starting a simple HTTP server on port +8000 so that you can connect and see your changes. Just run ``docker +build .`` and run the resulting image. This is the equivalent to +``make clean server`` since each container starts clean. + +In the ``docs/`` directory, run: + ```docker build -t docker:docs . && docker run -p 8000:8000 docker:docs``` + Usage ----- -* Change the `.rst` files with your favorite editor to your liking. -* Run `make docs` to clean up old files and generate new ones. -* Your static website can now be found in the `_build` directory. -* To preview what you have generated run `make server` and open http://localhost:8000/ in your favorite browser. +* Follow the contribution guidelines (``../CONTRIBUTING.md``) +* Work in your own fork of the code, we accept pull requests. +* Change the ``.rst`` files with your favorite editor -- try to keep the + lines short and respect RST and Sphinx conventions. +* Run ``make clean docs`` to clean up old files and generate new ones, + or just ``make docs`` to update after small changes. +* Your static website can now be found in the ``_build`` directory. +* To preview what you have generated run ``make server`` and open + http://localhost:8000/ in your favorite browser. + +``make clean docs`` must complete without any warnings or errors.
