+# `google-crc32c`
+
+This package wraps the [`google/crc32c`](https://github.com/google/crc32c)
+hardware-based implementation of the CRC32C hashing algorithm. Multiple wheels
+are distributed as well as source. If a wheel is not published for the python
+version and platform you are using, you will need to compile crc32c using a
+C toolchain.
+
+
+# Building
+
+## Be sure to check out all submodules:
+
+```
+$ git clone --recursive https://github.com/googleapis/python-crc32c
+```
+
+## Prerequisites
+
+On Linux:
+
+- `docker`
+- `python3.7`
+
+On OS X:
+
+- `make`
+- [Official][1] `python.org` Python 2.7, 3.5, 3.6 and 3.7
+
+On Windows:
+
+- `cmake`
+- [Official][1] `python.org` Python 3.5, 3.6 and 3.7
+- Visual Studio 15 2017 (just the compiler toolchain)
+
+Unfortunately, `libcrc32c` relies on many C++11 features, so
+building a Python 2.7 extension with the
+[Visual C++ Compiler for Python 2.7][2] is infeasible.
+
+
+## Building Wheels
+
+On Linux:
+
+```
+./scripts/manylinux/build.sh
+```
+
+On OS X:
+
+```
+./scripts/osx/build.sh
+```
+
+On Windows: see `.appveyor.yml`.
+
+## Testing/Verify Wheels
+
+On Linux (i.e. a host OS, not a `docker` container):
+
+```
+$ ./scripts/manylinux/check-37.sh
+...
+ venv/bin/python check_cffi_crc32c.py
+_crc32c_cffi: <module 'crc32c._crc32c_cffi' from '.../python-crc32c/venv/lib/python3.7/site-packages/crc32c/_crc32c_cffi.abi3.so'>

+
+## Installing locally for testing
+
+Initialize the submodules and build the main `libcrc32c.so` shared
+library using `cmake` / `make`:
+
+```bash
+$ cd python-crc32c
+$ git submodule update --init --recursive
+$ python -m venv venv
+$ venv/bin/pip install --upgrade setuptools pip wheel
+$ venv/bin/pip install cmake
+$ mkdir usr
+$ export CRC32C_INSTALL_PREFIX=$(pwd)/usr
+$ mkdir google_crc32c/build
+$ cd google_crc32c/build
+$ ../../venv/bin/cmake \
+>   -DCRC32C_BUILD_TESTS=no \
+>   -DCRC32C_BUILD_BENCHMARKS=no \
+>   -DBUILD_SHARED_LIBS=yes \
+>   -DCMAKE_INSTALL_PREFIX:PATH=${CRC32C_INSTALL_PREFIX} \
+>   ..
+$ make all install
+$ cd ../..
+```
+
+Now, run the tests:
+
+```bash
+$ venv/bin/pip install -e .[testing]
+$ venv/bin/py.test tests/
