+Boost Config Library
+============================
+
+This library provides configuration support for the Boost C++ libraries.
+
+The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/config/index.html).
+
+|                  |  Master  |   Develop   |
+|------------------|----------|-------------|
+| Travis           | [![Build Status](https://travis-ci.org/boostorg/config.svg?branch=master)](https://travis-ci.org/boostorg/config)  |  [![Build Status](https://travis-ci.org/boostorg/config.png)](https://travis-ci.org/boostorg/config) |

+
+## Support, bugs and feature requests ##
+
+Bugs and feature requests can be reported through the [Gitub issue tracker](https://github.com/boostorg/config/issues)
+(see [open issues](https://github.com/boostorg/config/issues) and
+[closed issues](https://github.com/boostorg/config/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed)).
+
+You can submit your changes through a [pull request](https://github.com/boostorg/config/pulls).
+
+There is no mailing-list specific to Boost Config, although you can use the general-purpose Boost [mailing-list](http://lists.boost.org/mailman/listinfo.cgi/boost-users) using the tag [config].
+
+
+## Development ##
+
+Clone the whole boost project, which includes the individual Boost projects as submodules ([see boost+git doc](https://github.com/boostorg/boost/wiki/Getting-Started)): 
+
+    git clone https://github.com/boostorg/boost
+    cd boost
+    git submodule update --init
+
+The Boost Config Library is located in `libs/config/`. 
+
+### Running tests ###
+First, make sure you are in `libs/config/test`. 
+You can either run all the tests listed in `Jamfile.v2` or run a single test:
+
+    ../../../b2                        <- run all tests
+    ../../../b2 config_info            <- single test
+
+### For developers ###
+Please check the [Guidelines for Boost Authors](http://www.boost.org/doc/libs/release/libs/config/doc/html/boost_config/guidelines_for_boost_authors.html). from the full documentation.
