+### Linux builds on Docker
+
+Linux wheels are built in the [`manylinux1` docker images](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 513](https://www.python.org/dev/peps/pep-0513/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
+- Programs and libraries cannot be installed on the Travis CI Ubuntu host with `apt-get`, but can be installed inside of the Docker image using `yum` or manually. The same goes for environment variables that are potentially needed to customize the wheel building. `cibuildwheel` supports this by providing the `CIBW_ENVIRONMENT` and `CIBW_BEFORE_BUILD` options to setup the build environment inside the running Docker image. See [below](#options) for details on these options.
+- The project directory is mounted in the running Docker instance as `/project`, the output directory for the wheels as `/output`. In general, this is handled transparently by `cibuildwheel`. For a more finegrained level of control however, the root of the host file system is mounted as `/host`, allowing for example to access shared files, caches, etc. on the host file system.  Note that this is not available on CircleCI due to their Docker policies.
+- Alternative dockers images can be specified with the `CIBW_MANYLINUX1_X86_64_IMAGE` and `CIBW_MANYLINUX1_I686_IMAGE` options to allow for a custom, preconfigured build environment for the Linux builds. See [below](#options) for more details.

 ### 0.4.0
 
-- Fixed a bug that was increasing the build time by building the wheel twice. This was a problem for large projects that have a long build time. If you're upgrading and you need the old behaviour, use `CIBW_BEFORE_BUILD={pip} install .`, or install exactly the dependencies you need in `CIBW_BEFORE_BUILD`. See #18.

+If you'd like to keep wheel building separate from the package itself, check out [astrofrog/autowheel](https://github.com/astrofrog/autowheel). It builds packages using cibuildwheel from source distributions on PyPI.
+
 If `cibuildwheel` is too limited for your needs, consider [matthew-brett/multibuild](http://github.com/matthew-brett/multibuild). `multibuild` is a toolbox for building a wheel on various platforms. It can do a lot more than this project - it's used to build SciPy!
