+CMake Caches
+============
+
+This directory contains CMake cache scripts that pre-populate the CMakeCache in
+a build directory with commonly used settings.
+
+The first two cache files in the directory are used by Apple to build the clang
+distribution packaged with Xcode. You can use the caches with the following
+CMake invocation:
+
+cmake -G <build system>
+  -C <path to llvm>/tools/clang/cmake/caches/Apple-stage1.cmake
+  -DCMAKE_BUILD_TYPE=Release
+  [-DCMAKE_INSTALL_PREFIX=<install path>]
+  <path to llvm>
+
+Building the `bootstrap` target from this generation will build clang, and
+`bootstrap-install` will install it.
