 #### Manylinux
 
-If you want to build .whl files that are compatible with a wide range of Linux distributions and can be uploaded to PyPI, using a [manylinux](https://github.com/pypa/manylinux) container is necessary. 
-
-This example assumes a manylinux2014 (x86_64) target, using other docker base images should work to compile for other targets. Go into the `rustfrc/docker` directory and run:
-```shell
-docker pull quay.io/pypa/manylinux2014_x86_64
-docker build --no-cache -t tmtenbrink/manylinux2014-rustfrc --build-arg PY_ABI=cp39-cp39 .
-```
-
-After the image is built, run it as a container:
-```shell
-docker run -it tmtenbrink/manylinux2014-rustfrc
-```
-
-The repository should now be installed at `/opt/rustfrc`, with its dependencies and `maturin` installed. Then follow the same steps as above, but when the wheels are built run the following, which should resolve any issues: 
-```shell
-find . -name '*.whl' -exec auditwheel repair {} \;
-```
-
-The complete wheel files can now be found in a `/wheelhouse` directory.
-
-Take a look at the GitHub Actions for this project for an idea of how to automate this.
