Documentation updated (#59).

README.md

 The namespace `sr` is used instead of `std`.
 
 ###### Filenames
-The filenames contain a `.h` extension.
-
-These deviations are necessary through standard requirements.
+The filenames contain a `.h` extension. To enable the compatible header as specified in the document the CMake option `ENABLE_COMPAT_HEADER` can be used. This will generate and install an additional header named `scope` (without file extension).
 
 ###### std::uncaught_exceptions()
 The function `std::uncaught_exceptions()` is not available in C++14 and is therefore replaced with `std::uncaught_exception()`. This has some limitations, but is the only solution until C++17 is used.
