+## Standalone Mode ##
+
+ This library may now be used in "standalone" mode without the rest of the Boost C++ libraries, in order to do this you must either:
+
+* Have a C++17 compiler that supports __has_include, in this case if <boost/config.hpp> is not present then the library will automoatically enter standalone mode. Or:
+* Define BOOST_REGEX_STANDALONE when building.
+
+The main difference between the 2 modes, is that when Boost.Config is present the library will automatically configure itself around various compiler defects. In particular in order to use the library with exception support turned off, you will either need a copy of Boost.Config in your include path, or else manually define BOOST_NO_EXCEPTIONS when building.
+
+In any event, to obtain a standalone version of this library, simply download a .zip of the "master" branch of this repository.

+The library comes with a very basic CMakeLists.txt that allows this library to be used from other CMake scripts.
+
+CMakeLists.txt defines two targets:
+
+* `Boost::regex`  This is the target to use for normal header only builds.
+* `Boost::regex_icu`  This is the target to use if you are using `<boost/regex/icu.hpp>` in your code, and wish to have the ICU dependencies taken care of for you.
+
+There is also one configuration option:
+
+* BOOST_REGEX_STANDALONE when set then no other Boost libraries are targeted as dependencies, and Boost.Regex is placed in standalone mode.  Invoke CMake
