+Boost StaticAssert Library
+============================
+
+The Boost StaticAssert library provides static assertions for C++, this library is the ancestor to C++ native static_assert's and 
+can be used on older compilers which don't have that feature.
+
+The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/static_assert).
+
+## Support, bugs and feature requests ##
+
+Bugs and feature requests can be reported through the [Gitub issue tracker](https://github.com/boostorg/static_assert/issues)
+(see [open issues](https://github.com/boostorg/static_assert/issues) and
+[closed issues](https://github.com/boostorg/static_assert/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed)).
+
+You can submit your changes through a [pull request](https://github.com/boostorg/static_assert/pulls).
+
+There is no mailing-list specific to Boost StaticAssert, although you can use the general-purpose Boost [mailing-list](http://lists.boost.org/mailman/listinfo.cgi/boost-users) using the tag [static_assert].
+
+
+## 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 StaticAssert Library is located in `libs/static_assert/`. 
+
+### Running tests ###
+First, make sure you are in `libs/static_assert/test`. 
+You can either run all the tests listed in `Jamfile.v2` or run a single test:
+
+    ../../../b2                        <- run all tests
+    ../../../b2 static_assert_test     <- single test
+
