Add Brotli logo to README head (#535)
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.
Brotli is open-sourced under the MIT License, see the LICENSE file.
Brotli mailing list: https://groups.google.com/forum/#!forum/brotli
To build and run tests, simply do:
$ ./configure && make
If you want to install brotli, use one of the more advanced build systems below.
See Bazel
The basic commands to build, test and install brotli are:
$ mkdir out && cd out && ../configure-cmake && make
$ make test
$ make install
You can use other CMake configuration. For example, to build static libraries and use a custom installation directory:
$ mkdir out-static && \
cd out-static && \
../configure-cmake --disable-shared-libs --prefix='/my/prefix/dir/'
$ make install
See Premake5
To install the Python module from source, run the following:
$ python setup.py install
See the Python readme for more details on testing and development.
Independent decoder implementation by Mark Adler, based entirely on format specification.
JavaScript port of brotli decoder. Could be used directly via npm install brotli

### 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://www.ietf.org/rfc/rfc7932.txt).
