-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
-
