+# Boost.Function, a polymorphic function wrapper
+
+[Boost.Function](http://boost.org/libs/function), part of the
+[Boost C++ Libraries](http://boost.org), is the original implementation of the
+polymorphic function wrapper `boost::function`, which was eventually accepted
+into the C++11 standard as [`std::function`](https://en.cppreference.com/w/cpp/utility/functional/function).
+
+## Currently supported compilers
+
+* g++ 4.8 or later
+* clang++ 3.9 or later
+* Visual Studio 2005-2022
+
+Tested on [Github Actions](https://github.com/boostorg/function/actions) and [Appveyor](https://ci.appveyor.com/project/pdimov/function/).
