### Introduction

Brotli is a generic-purpose lossless compression algorithm that compresses data
using a combination of a modern variant of the LZ77 algorithm, Huffman coding
and 2nd order context modeling, with a compression ratio comparable to the best
currently available general-purpose compression methods. It is similar in speed
with deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in [RFC 7932](https://tools.ietf.org/html/rfc7932).

Brotli is open-sourced under the MIT License, see the LICENSE file.

> **Please note:** brotli is a "stream" format; it does not contain
> meta-information, like checksums or uncompressed data length. It is possible
> to modify "raw" ranges of the compressed stream and the decoder will not
> notice that.

### Build instructions

#### Vcpkg

You can download and install brotli using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:

    git clone https://github.com/Microsoft/vcpkg.git
    cd vcpkg
    ./bootstrap-vcpkg.sh
    ./vcpkg integrate install
    ./vcpkg install brotli

The brotli port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.

#### Bazel

See [Bazel](http://www.bazel.build/)

#### CMake

The basic commands to build and install brotli are:

    $ mkdir out && cd out
    $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed ..
    $ cmake --build . --config Release --target install

You can use other [CMake](https://cmake.org/) configuration.

#### Python

To install the latest release of the Python module, run the following:

    $ pip install brotli

To install the tip-of-the-tree version, run:

    $ pip install --upgrade git+https://github.com/google/brotli

See the [Python readme](python/README.md) for more details on installing
from source, development, and testing.
