-From the root of the source tree:
+If you are using CMake, the easiest way to include mstch in your project is to 
+copy the whole directory to your source tree, and use `add_subdirectory` in your 
+CMakeLists.txt. This will set a variable named `mstch_INCLUDE_DIR` that contains 
+its include path, and add a static library target named mstch. For example:
+
+```cmake
+add_subdirectory(external/mstch)
+
+include_directories(${mstch_INCLUDE_DIR})
+
+target_link_libraries(your_project mstch)
+```
