-- Builds manylinux, macOS and Windows (32 and 64bit) wheels using Travis CI and Appveyor
+> ¹ Not supported on Travis
+
+- Builds manylinux, macOS and Windows (32 and 64bit) wheels using Azure Pipelines, Travis CI, AppVeyor, and CircleCI
 - Bundles shared library dependencies on Linux and macOS through [auditwheel](https://github.com/pypa/auditwheel) and [delocate](https://github.com/matthew-brett/delocate)
 - Runs the library test suite against the wheel-installed version of your library
 
 Usage
 -----
 
-`cibuildwheel` currently works on **Travis CI** to build Linux and Mac wheels, and **Appveyor** to build Windows wheels.
+`cibuildwheel` currently works on **Travis CI** and **Azure Pipelines** to build wheels for all three supported platforms (Linux, macOS, Windows). On **CircleCI** Linux and macOS wheels can be built, and on **AppVeyor** Windows is supported.
 
-`cibuildwheel` is not intended to run on your development machine. It will try to install packages globally; this is no good. Travis CI and Appveyor run their builds in isolated environments, so are ideal for this kind of script.
+|                 | Linux | macOS | Windows |
+|-----------------|-------|-------|---------|
+| Azure Pipelines | ✅    | ✅    | ✅      |
+| Travis CI       | ✅    | ✅    | ✅      |
+| AppVeyor        |       |       | ✅      |
+| CircleCI        | ✅    | ✅    |         |
 
-### Minimal setup
+`cibuildwheel` is not intended to run on your development machine. Because it uses system Python from Python.org it will try to install packages globally - not what you expect from a build tool! Instead, isolated CI services like Travis CI, CircleCI, Azure Pipelines and AppVeyor are ideal.
 
-- Create a `.travis.yml` file in your repo.

+Example setup
+-------------
 
-    script:
-      - pip install cibuildwheel==0.1.3
-      - cibuildwheel --output-dir wheelhouse
-    ```
+To build manylinux and macOS wheels on Travis CI, and upload them to PyPI whenever you tag a version, you could use this `.travis.yml`:
 
-  Then setup a deployment method by following the [Travis CI deployment docs](https://docs.travis-ci.com/user/deployment/).
+```yaml
+language: python
 
-- Create an `appveyor.yml` file in your repo.

+  include:
+    # perform a linux build
+    - sudo: required
+      services:

-    artifacts:
-      - path: "wheelhouse\\*.whl"
-        name: Wheels
-    ```
-    
-  Appveyor will store the built wheels for you - you can access them from the project console. Alternatively, you may want to store them in the same place as the Travis CI build. See [Appveyor deployment docs](https://www.appveyor.com/docs/deployment/) for more info.
-    
-- Commit those files, enable building of your repo on Travis CI and Appveyor, and push.

-                    [project_dir]
-    
-Build wheels for all the platforms.
-
-positional arguments:
-  project_dir           Path to the project that you want wheels for.
-                        Default: the current directory.
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --platform {auto,linux,macos,windows}
-                        Platform to build for. For "linux" you need docker
-                        running, on Mac or Linux. For "macos", you need a Mac
-                        machine, and note that this script is going to
-                        automatically install MacPython on your system, so
-                        don't run on your development machine. For "windows",
-                        you need to run in Windows, and it will build and test
-                        for all versions of Python at C:\PythonXX[-x64].
-  --output-dir OUTPUT_DIR
-                        Destination folder for the wheels. 
-
-```
-
-Most of the config is via environment variables. These go into `.travis.yml` and `appveyor.yml` nicely.
-
-| Environment variable: `CIBW_PLATFORM` | Command line argument: `--platform`
-| --- | ---
-
-Options: `auto` `linux` `macos` `windows`
-
-Default: `auto`
-
-`auto` will auto-detect platform using environment variables, such as `TRAVIS_OS_NAME`/`APPVEYOR`.
-
-For `linux` you need Docker running, on Mac or Linux. For `macos`, you need a Mac machine, and note that this script is going to automatically install MacPython on your system, so don't run on your development machine. For `windows`, you need to run in Windows, and it will build and test for all versions of Python at `C:\PythonXX[-x64]`.
-
-| Environment variable: `CIBW_TEST_COMMAND`
-| ---
-
-Optional.
-
-Shell command to run the tests. The project root should be included in the command as "{project}". The wheel will be installed automatically and available for import from the tests.
-
-Example: `nosetests {project}/tests`
-
-| Environment variable: `CIBW_TEST_REQUIRES`
-| ---
-
-Optional.
-
-Space-separated list of dependencies required for running the tests.
-
-Example: `pytest`  
-Example: `nose==1.3.7 moto==0.4.31`
-
-| Environment variable: `CIBW_SKIP` | 🔶 coming soon 🔶
-| --- | ---
-
-Optional.
-
-Space-separated list of builds to skip. Each build has an identifier like `cp27-linux_x86_64` or `cp34-macosx_10_6_intel` - you can list ones to skip here and `cibuildwheel` won't try to build them.
-
-The format is `python_tag-platform_tag`. The tags are as defined in [PEP 0425](https://www.python.org/dev/peps/pep-0425/#details).
-
-Python tags look like `cp27` `cp34` `cp35` `cp36`
-
-Platform tags look like `macosx_10_6_intel` `linux_x86_64` `linux_i386` `win32` `win_amd64`
-
-You can also use shell-style globbing syntax (as per `fnmatch`) 
-
-Example: `cp27-macosx_10_6_intel `  (don't build on Python 2 on Mac)  
-Example: `cp27-win*`  (don't build on Python 2.7 on Windows)  
-Example: `cp34-*`  (don't build on Python 3.4)  
-

-
-#### Example YML syntax
-
-<table>
-<tr><td><i>example .travis.yml environment variables</i><pre><code>env:
-  global:
-    - CIBW_TEST_REQUIRES=nose

-</tr></table>
-
-Delivering to PyPI
-------------------
-
-After you've built your wheels, you'll probably want to deliver them to PyPI.
-
-### Manual method
-
-On your development machine, do the following...
-
-```bash
-# Clear out your 'dist' folder. 
-rm -rf dist
-# Make a source distribution
-python setup.py sdist
-
-# 🏃🏻
-# Go and download your wheel files from wherever you put them. Put 
-# them all into the 'dist' folder.
-
-# Upload using 'twine' (you may need to 'pip install twine')
-twine upload dist/*
-```
-
-### Semi-automatic method using wheelhouse-uploader
-
-Obviously, manual steps are for chumps, so we can automate this a little by using [wheelhouse-uploader](https://github.com/ogrisel/wheelhouse-uploader).
-
-> Quick note from me - using S3 as a storage didn't work due to a [bug](https://issues.apache.org/jira/browse/LIBCLOUD-792) in libcloud. Feel free to use my fork of that package that fixes the bug `pip install https://github.com/joerick/libcloud/archive/v1.5.0-s3fix.zip`
-
-It didn't work!
----------------
-
-If your wheel didn't compile, check the list below for some debugging tips.
-
-- A mistake in your config. To quickly test your config without doing a git push and waiting for your code to build on CI, you can run the Linux build in a Docker container. On Mac or Linux, with Docker running, try `cibuildwheel --platform linux`. You'll have to bring your config into the current environment first.
-- Missing dependency. You might need to install something on the build machine. You can do this in `.travis.yml` or `appveyor.yml`, with apt-get, brew or whatever Windows uses :P . Given how the Linux build works, we'll probably have to build something into `cibuildwheel`. Let's chat about that over in the issues!
-- Windows: missing C feature. The Windows C compiler doesn't support C language features invented after 1990, so you'll have to backport your C code to C90. For me, this mostly involved putting my variable declarations at the top of the function like an animal.

-Since `cibuildwheel` runs the wheel through delocate or auditwheel, it will automatically bundle library dependencies. This is similar to static linking - it might have some licence implications. Check the license for any code you're pulling in to make sure that's allowed.

 Contributing
 ============
 
-Wheel-building is pretty complex. I expect users to find many edge-cases - please help the rest of the community out by documenting these, adding features to support them, and reporting bugs.
+For more info on how to contribute to cibuildwheel, see the [docs](https://cibuildwheel.readthedocs.io/en/latest/contributing/).
 
-I plan to be pretty liberal in accepting pull requests, as long as they align with the design goals below.
+Maintainers
+-----------
 
-`cibuildwheel` is indie open source. I'm not paid to work on this.
-
-Design Goals
-------------
-
-- `cibuildwheel` should wrap the complexity of wheel building.
-- The user interface to `cibuildwheel` is the build script (e.g. `.travis.yml`). Feature additions should not increase the complexity of this script.
-- Options should be environment variables (these lend themselves better to YML config files). They should be prefixed with `CIBW_`.
-- Options should be generalise to all platforms. If platform-specific options are required, they should be namespaced e.g. `CIBW_TEST_COMMAND_MACOS`
-
-Other notes:
-
-- The platforms are very similar, until they're not. I'd rather have straight-forward code than totally DRY code, so let's keep airy platfrom abstractions to a minimum.
-- I might want to break the options into a shared config file one day, so that config is more easily shared. That has motivated some of the design decisions.

+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!

+title: Contributing
+---
+
+Wheel-building can be pretty complex. I expect users to find many edge-cases - please help the rest of the community out by documenting these, adding features to support them, and reporting bugs.
+
+I plan to be pretty liberal in accepting pull requests, as long as they align with the design goals below.
+
+`cibuildwheel` is indie open source. We're not paid to work on this.
+
+Design Goals
+------------
+
+- `cibuildwheel` should wrap the complexity of wheel building.
+- The user interface to `cibuildwheel` is the build script (e.g. `.travis.yml`). Feature additions should not increase the complexity of this script.
+- Options should be environment variables (these lend themselves better to YML config files). They should be prefixed with `CIBW_`.
+- Options should be generalise to all platforms. If platform-specific options are required, they should be namespaced e.g. `CIBW_TEST_COMMAND_MACOS`
+
+Other notes:
+
+- The platforms are very similar, until they're not. I'd rather have straight-forward code than totally DRY code, so let's keep airy platfrom abstractions to a minimum.
+- I might want to break the options into a shared config file one day, so that config is more easily shared. That has motivated some of the design decisions.
+
+### cibuildwheel's relationship with build errors
+
+cibuildwheel doesn't really do anything itself - it's always deferring to other tools (pip, wheel, auditwheel, delocate, docker). Without cibuildwheel, the process is really fragmented. Different tools, across different OSs need to be stitched together in just the right way to make it work.
+
+We're not responsible for errors in those tools, for fixing errors/crashes there. But cibuildwheel's job is providing users with an 'integrated' user experience across those tools. We provide an abstraction. The user says 'build me some wheels', not 'open the docker container, build a wheel with pip, fix up the symbols with auditwheel' etc.  However, errors have a habit of breaking abstractions. And this is where users get confused, because the mechanism of cibuildwheel is laid bare, and they must understand a little bit how it works to debug.
+
+So, if we can, I'd like to improve the experience on errors as well. In [this](https://github.com/joerick/cibuildwheel/issues/139) case, it takes a bit of knowledge to understand that the linux builds are happening in a totally different OS via docker, that the linked symbols won't match, that auditwheel will fail because of this. A problem with how the tools fit together, instead of the tools themselves.

+title: Delivering to PyPI
+---
+
+After you've built your wheels, you'll probably want to deliver them to PyPI.
+
+### Manual method
+
+On your development machine, do the following...
+
+```bash
+# Clear out your 'dist' folder. 
+rm -rf dist
+# Make a source distribution
+python setup.py sdist
+
+# 🏃🏻
+# Go and download your wheel files from wherever you put them. e.g. your CI
+# provider can be configured to store them for you. Put them all into the 
+# 'dist' folder.
+
+# Upload using 'twine' (you may need to 'pip install twine')
+twine upload dist/*
+```
+
+### Semi-automatic method using wheelhouse-uploader
+
+Obviously, manual steps are for chumps, so we can automate this a little by using [wheelhouse-uploader](https://github.com/ogrisel/wheelhouse-uploader).
+
+> Quick note from me - using S3 as a storage didn't work due to a [bug](https://issues.apache.org/jira/browse/LIBCLOUD-792) in libcloud. Feel free to use my fork of that package that fixes the bug `pip install https://github.com/joerick/libcloud/archive/v1.5.0-s3fix.zip`
+
+### Automatic method
+
+If you don't need much control over the release of a package, you can set up cibuildwheel to deliver the wheels straight to PyPI. This doesn't require anycloud storage to work - you just need to bump the version and tag it.
+
+Check out [this example repo](https://github.com/joerick/cibuildwheel-autopypi-example) for instructions on how to set this up.

+title: Tips and tricks
+---
+
+### Troubleshooting
+
+If your wheel didn't compile, check the list below for some debugging tips.
+
+- A mistake in your config. To quickly test your config without doing a git push and waiting for your code to build on CI, you can test the Linux build in a Docker container. On Mac or Linux, with Docker running, try `cibuildwheel --platform linux`. You'll have to bring your config into the current environment first.
+
+- Missing dependency. You might need to install something on the build machine. You can do this in `.travis.yml`, `appveyor.yml`, or `.circleci/config.yml`, with apt-get, brew or choco. Given how the Linux build works, you'll need to use the [`CIBW_BEFORE_BUILD`](options.md#before-build) option.
+
+- Windows: missing C feature. The Windows C compiler doesn't support C language features invented after 1990, so you'll have to backport your C code to C90. For me, this mostly involved putting my variable declarations at the top of the function like an animal.
+
+- MacOS: calling cibuildwheel from a python3 script and getting a `ModuleNotFoundError`? Due to a [bug](https://bugs.python.org/issue22490) in CPython, you'll need to [unset the `__PYVENV_LAUNCHER__` variable](https://github.com/joerick/cibuildwheel/issues/133#issuecomment-478288597) before activating a venv.
+
+### Linux builds on Docker
+
+Linux wheels are built in the [`manylinux` docker images](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 571](https://www.python.org/dev/peps/pep-0571/). 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 [the options docs](options.md#build-environment) 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_MANYLINUX_X86_64_IMAGE` and `CIBW_MANYLINUX_I686_IMAGE` options to allow for a custom, preconfigured build environment for the Linux builds. See [options](options.md#manylinux-image) for more details.
+
+### Building packages with optional C extensions
+
+`cibuildwheel` defines the environment variable `CIBUILDWHEEL` to the value `1` allowing projects for which the C extension is optional to make it mandatory when building wheels.
+
+An easy way to do it in Python 3 is through the `optional` named argument of `Extension` constructor in your `setup.py`:
+
+```python
+myextension = Extension(
+    "myextension",
+    ["myextension.c"],
+    optional=os.environ.get('CIBUILDWHEEL', '0') != '1',
+)
+```

+## Options summary
+
+<div class="options-toc"></div>
+
+## Setting options
+
+cibuildwheel is configured using environment variables, that can be set using 
+your CI config.
+
+For example, to configure cibuildwheel to run tests, add the following YAML to
+your CI config file:
+
+> .travis.yml ([docs](https://docs.travis-ci.com/user/environment-variables/))
+```yaml
+env:
+  global:
+    - CIBW_TEST_REQUIRES=nose
+    - CIBW_TEST_COMMAND="nosetests {project}/tests"
+```
+
+> appveyor.yml ([docs](https://www.appveyor.com/docs/build-configuration/#environment-variables))
+```yaml
+environment:
+  global:
+    CIBW_TEST_REQUIRES: nose
+    CIBW_TEST_COMMAND: "nosetests {project}\\tests"
+```
+
+> .circleci/config.yml ([docs](https://circleci.com/docs/2.0/configuration-reference/#environment))
+```yaml
+jobs:
+  job_name:
+    environment:
+      CIBW_TEST_REQUIRES: nose
+      CIBW_TEST_COMMAND: "nosetests {project}/tests"
+```
+
+> azure-pipelines.yml ([docs](https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables))
+```yaml
+variables:
+  CIBW_TEST_REQUIRES: nose
+  CIBW_TEST_COMMAND: "nosetests {project}/tests"
+```
+
+
+## Build selection
+
+
+### `CIBW_PLATFORM` {: #platform}
+
+> Override the auto-detected target platform
+
+Options: `auto` `linux` `macos` `windows`
+
+Default: `auto`
+
+`auto` will auto-detect platform using environment variables, such as `TRAVIS_OS_NAME`/`APPVEYOR`/`CIRCLECI`.
+
+For `linux` you need Docker running, on Mac or Linux. For `macos`, you need a Mac machine, and note that this script is going to automatically install MacPython on your system, so don't run on your development machine. For `windows`, you need to run in Windows, and it will build and test for all versions of Python at `C:\PythonXX[-x64]`.
+
+This option can also be set using the command-line option `--platform`.
+
+### `CIBW_BUILD`, `CIBW_SKIP` {: #build-skip}
+
+> Choose the Python versions to build
+
+Space-separated list of builds to build and skip. Each build has an identifier like `cp27-manylinux_x86_64` or `cp35-macosx_10_6_intel` - you can list specific ones to build and `cibuildwheel` will only build those, and/or list ones to skip and `cibuildwheel` won't try to build them.
+
+When both options are specified, both conditions are applied and only builds with a tag that matches `CIBW_BUILD` and does not match `CIBW_SKIP` will be built.
+
+When setting the options, you can use shell-style globbing syntax (as per `fnmatch`). All the build identifiers supported by cibuildwheel are shown below:
+
+<div class="build-id-table-marker"></div>
+
+|            | macOS 64bit             | macOS 32/64bit         | Manylinux 64bit        | Manylinux 32bit      | Windows 64bit   | Windows 32bit  |
+|------------|-------------------------|------------------------|------------------------|----------------------|-----------------|----------------|
+| Python 2.7 |                         | cp27-macosx_10_6_intel | cp27-manylinux_x86_64  | cp27-manylinux_i686  | cp27-win_amd64  | cp27-win32     |
+| Python 3.5 |                         | cp35-macosx_10_6_intel | cp35-manylinux_x86_64  | cp35-manylinux_i686  | cp35-win_amd64  | cp35-win32     |
+| Python 3.6 |                         | cp36-macosx_10_6_intel | cp36-manylinux_x86_64  | cp36-manylinux_i686  | cp36-win_amd64  | cp36-win32     |
+| Python 3.7 |                         | cp37-macosx_10_6_intel | cp37-manylinux_x86_64  | cp37-manylinux_i686  | cp37-win_amd64  | cp37-win32     |
+| Python 3.8 | cp38-macosx_10_9_x86_64 |                        | cp38-manylinux_x86_64  | cp38-manylinux_i686  | cp38-win_amd64  | cp38-win32     |
+
+The list of supported and currently selected build identifiers can also be retrieved by passing the `--print-build-identifiers` flag to `cibuildwheel`.
+The format is `python_tag-platform_tag`, with tags similar to those in [PEP 425](https://www.python.org/dev/peps/pep-0425/#details).
+
+#### Examples
+
+```yaml
+# Only build on Python 3.6
+CIBW_BUILD: cp36-*
+
+# Skip building on Python 2.7 on the Mac
+CIBW_SKIP: cp27-macosx_10_6_intel
+
+# Skip building on Python 3.8 on the Mac
+CIBW_SKIP: cp38-macosx_10_9_x86_64
+
+# Skip building on Python 2.7 on all platforms
+CIBW_SKIP: cp27-*
+
+# Skip Python 2.7 on Windows
+CIBW_SKIP: cp27-win*
+
+# Skip Python 2.7 on 32-bit Windows
+CIBW_SKIP: cp27-win32
+
+# Skip Python 2.7 and Python 3.5
+CIBW_SKIP: cp27-* cp35-*
+
+# Skip Python 3.6 on Linux
+CIBW_SKIP: cp36-manylinux*
+
+# Only build on Python 3 and skip 32-bit builds
+CIBW_BUILD: cp3?-*
+CIBW_SKIP: "*-win32 *-manylinux_i686"

+
+
+## Build customization
+
+
+### `CIBW_ENVIRONMENT` {: #environment}
+> Set environment variables needed during the build
+
+A space-separated list of environment variables to set during the build. Bash syntax should be used, even on Windows.
+
+You must set this variable to pass variables to Linux builds (since they execute in a Docker container). It also works for the other platforms.
+
+You can use `$PATH` syntax to insert other variables, or the `$(pwd)` syntax to insert the output of other shell commands.
+
+#### Examples
+```yaml
+# Set some compiler flags
+CIBW_ENVIRONMENT: "CFLAGS='-g -Wall' CXXFLAGS='-Wall'"
+
+# Append a directory to the PATH variable (this is expanded in the build environment)
+CIBW_ENVIRONMENT: "PATH=$PATH:/usr/local/bin"
+
+# Set BUILD_TIME to the output of the `date` command
+CIBW_ENVIRONMENT: "BUILD_TIME=$(date)"
+
+# Supply options to `pip` to affect how it downloads dependencies
+CIBW_ENVIRONMENT: "PIP_EXTRA_INDEX_URL=https://pypi.myorg.com/simple"
+```
+
+Platform-specific variants also available:  
+`CIBW_ENVIRONMENT_MACOS` | `CIBW_ENVIRONMENT_WINDOWS` | `CIBW_ENVIRONMENT_LINUX`
+
+!!! note
+    `cibuildwheel` always defines the environment variable `CIBUILDWHEEL=1`. This can be useful for [building wheels with optional extensions](faq.md#building-packages-with-optional-c-extensions).
+
+
+### `CIBW_BEFORE_BUILD` {: #before-build}
+> Execute a shell command preparing each wheel's build
+
+A shell command to run before building the wheel. This option allows you to run a command in **each** Python environment before the `pip wheel` command. This is useful if you need to set up some dependency so it's available during the build.
+
+If dependencies are required to build your wheel (for example if you include a header from a Python module), set this to `pip install .`, and the dependencies will be installed automatically by pip. However, this means your package will be built twice - if your package takes a long time to build, you might wish to manually list the dependencies here instead.
+
+The active Python binary can be accessed using `python`, and pip with `pip`; `cibuildwheel` makes sure the right version of Python and pip will be executed. `{project}` can be used as a placeholder for the absolute path to the project's root.
+
+#### Examples
+```yaml
+# install your project and dependencies before building
+CIBW_BEFORE_BUILD: pip install .
+
+# install something required for the build
+CIBW_BEFORE_BUILD: pip install pybind11
+
+# chain commands using &&
+CIBW_BEFORE_BUILD: yum install -y libffi-dev && pip install .
+```
+
+Platform-specific variants also available:  
+ `CIBW_BEFORE_BUILD_MACOS` | `CIBW_BEFORE_BUILD_WINDOWS` | `CIBW_BEFORE_BUILD_LINUX`
+
+
+### `CIBW_MANYLINUX_X86_64_IMAGE`, `CIBW_MANYLINUX_I686_IMAGE` {: #manylinux-image}
+> Specify alternative manylinux docker images 
+
+An alternative Docker image to be used for building [`manylinux`](https://github.com/pypa/manylinux) wheels. `cibuildwheel` will then pull these instead of the default images, [`quay.io/pypa/manylinux2010_x86_64`](https://quay.io/pypa/manylinux2010_x86_64) and [`quay.io/pypa/manylinux2010_i686`](https://quay.io/pypa/manylinux2010_i686).
+
+The value of this option can either be set to `manylinux1` or `manylinux2010` to use the [official `manylinux` images](https://github.com/pypa/manylinux), or any other valid Docker image name.
+
+Beware to specify a valid Docker image that can be used in the same way as the official, default Docker images: all necessary Python and pip versions need to be present in `/opt/python/`, and the `auditwheel` tool needs to be present for `cibuildwheel` to work. Apart from that, the architecture and relevant shared system libraries need to be manylinux1- or manylinux2010-compatible in order to produce valid `manylinux1`/`manylinux2010` wheels (see https://github.com/pypa/manylinux, [PEP 513](https://www.python.org/dev/peps/pep-0513/), and [PEP 571](https://www.python.org/dev/peps/pep-0571/) for more details).
+
+Note that `auditwheel` detects the version of the `manylinux` standard in the Docker image through the `AUDITWHEEL_PLAT` environment variable, as `cibuildwheel` has no way of detecting the correct `--plat` command line argument to pass to `auditwheel` for a custom image. If a Docker image does not correctly set this `AUDITWHEEL_PLAT` environment variable, the `CIBW_ENVIRONMENT` option can be used to do so (e.g., `CIBW_ENVIRONMENT="manylinux2010_$(uname -m)"`).
+
+#### Examples
+
+```yaml
+# build using the manylinux1 image to ensure manylinux1 wheels are produced
+CIBW_MANYLINUX_X86_64_IMAGE: manylinux1
+CIBW_MANYLINUX_I686_IMAGE: manylinux1
+
+# build using a different image from the docker registry
+CIBW_MANYLINUX_X86_64_IMAGE: dockcross/manylinux-x64
+CIBW_MANYLINUX_I686_IMAGE: dockcross/manylinux-x86
+```
+
+## Testing
+
+### `CIBW_TEST_COMMAND` {: #test-command}
+> Execute a shell command to test all built wheels
+
+Shell command to run tests after the build. The wheel will be installed automatically and available for import from the tests. `{project}` can be used as a placeholder for the absolute path to the project's root and will be replaced by `cibuildwheel`.
+
+On Linux and Mac, the command runs in a shell, so you can write things like `cmd1 && cmd2`. 
+
+#### Examples
+
+```yaml
+# run the project tests against the installed wheel using `nose`
+CIBW_TEST_COMMAND: nosetests {project}/tests
+
+# run the project tests using `pytest`
+CIBW_TEST_COMMAND: nosetests {project}/tests
+```
+
+Platform-specific variants also available:  
+`CIBW_TEST_COMMAND_MACOS` | `CIBW_TEST_COMMAND_WINDOWS` | `CIBW_TEST_COMMAND_LINUX`
+
+
+### `CIBW_TEST_REQUIRES` {: #test-requires}
+> Install Python dependencies before running the tests
+
+Space-separated list of dependencies required for running the tests.
+
+#### Examples
+
+```yaml
+# install pytest before running CIBW_TEST_COMMAND
+CIBW_TEST_REQUIRES: pytest  
+
+# install specific versions of test dependencies
+CIBW_TEST_REQUIRES: nose==1.3.7 moto==0.4.31
+```
+
+Platform-specific variants also available:  
+`CIBW_TEST_REQUIRES_MACOS` | `CIBW_TEST_REQUIRES_WINDOWS` | `CIBW_TEST_REQUIRES_LINUX`
+
+### `CIBW_TEST_EXTRAS` {: #test-extras}
+> Install your wheel for testing using `extras_require`
+
+Comma-separated list of
+[extras_require](https://setuptools.readthedocs.io/en/latest/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies)
+options that should be included when installing the wheel prior to running the
+tests. This can be used to avoid having to redefine test dependencies in
+`CIBW_TEST_REQUIRES` if they are already defined in `setup.py` or
+`setup.cfg`.
+
+#### Examples
+
+```yaml
+# will cause the wheel to be installed with `pip install <wheel_file>[test,qt]`
+CIBW_TEST_EXTRAS: test,qt 
+```
+
+Platform-specific variants also available:  
+`CIBW_TEST_EXTRAS_MACOS` | `CIBW_TEST_EXTRAS_WINDOWS` | `CIBW_TEST_EXTRAS_LINUX`
+
+## Other
+
+### `CIBW_BUILD_VERBOSITY` {: #build-verbosity}
+> Increase/decrease the output of pip wheel
+
+An number from 1 to 3 to increase the level of verbosity (corresponding to invoking pip with `-v`, `-vv`, and `-vvv`), between -1 and -3 (`-q`, `-qq`, and `-qqq`), or just 0 (default verbosity). These flags are useful while debugging a build when the output of the actual build invoked by `pip wheel` is required.
+
+#### Examples
+
+```yaml
+# increase pip debugging output
+CIBW_BUILD_VERBOSITY: 1
+```
+
+Platform-specific variants also available:  
+`CIBW_BUILD_VERBOSITY_MACOS` | `CIBW_BUILD_VERBOSITY_WINDOWS` | `CIBW_BUILD_VERBOSITY_LINUX`
+
+## Command line options
+
+```text

+
+positional arguments:
+  project_dir           Path to the project that you want wheels for.
+                        Default: the current directory.
+
+optional arguments:
+  -h, --help            show this help message and exit
+  --platform {auto,linux,macos,windows}
+                        Platform to build for. For "linux" you need docker
+                        running, on Mac or Linux. For "macos", you need a Mac
+                        machine, and note that this script is going to
+                        automatically install MacPython on your system, so
+                        don't run on your development machine. For "windows",
+                        you need to run in Windows, and it will build and test
+                        for all versions of Python at C:\PythonXX[-x64].
+  --output-dir OUTPUT_DIR
+                        Destination folder for the wheels.
+  --print-build-identifiers
+                        Print the build identifiers matched by the current
+                        invocation and exit.

+
+# Travis CI [linux/mac] {: #travis-ci}
+
+To build Linux and Mac wheels on Travis CI, create a `.travis.yml` file in your repo.
+
+> .travis.yml
+```yaml
+language: python
+
+matrix:
+  include:
+    - sudo: required
+      services:
+        - docker
+      env: PIP=pip
+    - os: osx
+      language: generic
+      env: PIP=pip2
+
+script:
+  - $PIP install cibuildwheel==1.0.0
+  - cibuildwheel --output-dir wheelhouse
+```
+
+To build on Windows too, add this matrix entry:
+```yaml
+    - os: windows
+      language: shell
+      before_install:
+        - choco install python3 --version 3.6.8 --no-progress -y
+      env:
+        - PATH=/c/Python36:/c/Python36/Scripts:$PATH
+```
+
+Note that building Windows Python 2.7 wheels on Travis is unsupported.
+
+Commit this file, enable building of your repo on Travis CI, and push.
+
+Then setup a deployment method by following the [Travis CI deployment docs](https://docs.travis-ci.com/user/deployment/), or see [Delivering to PyPI](deliver-to-pypi.md). For more info on `.travis.yml`, check out the [docs](https://docs.travis-ci.com/).
+
+# CircleCI [linux/mac] {: #circleci}
+
+To build Linux and Mac wheels on CircleCI, create a `.circleci/config.yml` file in your repo,

+
+Commit this file, enable building of your repo on CircleCI, and push.
+
+!!! note
+    CircleCI doesn't enable free macOS containers for open source by default, but you can ask for access. See [here](https://circleci.com/docs/2.0/oss/#overview) for more information.
+
+CircleCI will store the built wheels for you - you can access them from the project console. Check out the CircleCI [docs](https://circleci.com/docs/2.0/configuration-reference/#section=configuration) for more info on this config file.
+
+# AppVeyor [windows] {: #appveyor}
+
+To build Windows wheels on AppVeyor, create an `appveyor.yml` file in your repo.
+
+> appveyor.yml
+
+```yaml
+build_script:
+  - pip install cibuildwheel==1.0.0
+  - cibuildwheel --output-dir wheelhouse
+artifacts:
+  - path: "wheelhouse\\*.whl"
+    name: Wheels
+```
+
+Commit this file, enable building of your repo on AppVeyor, and push.
+
+AppVeyor will store the built wheels for you - you can access them from the project console. Alternatively, you may want to store them in the same place as the Travis CI build. See [AppVeyor deployment docs](https://www.appveyor.com/docs/deployment/) for more info, or see [Delivering to PyPI](deliver-to-pypi.md) below.
