+# Building the OpenCL ICD Loader and Tests
+
+The build system will build ICD Loader library (OpenCL.dll or libOpenCL.so), the
+ICD Loader Test binary (icd_loader_test), and some helper libraries for the test.
+
+## Linux
+
+Run "make"
+
+## Windows
+
+Run "build_using_cmake.bat"
+
+## Running ICD Test
+
+The ICD Test can be run using ctest, which is a companion to cmake. It can also be
+run directly by executing icd_loader_test(.exe) executable from the bin folder.
+
+### Linux
+
+1. Add driver stub as an ICD
+    echo full/path/to/libOpenCLDriverStub.so > /etc/OpenCL/vendors/test.icd
+
+2. Run test using ctest
+    make test
+
+### Windows
+
+1. Add driver stub as an ICD by adding appropriate registry value
+    Key for 32-bit apps: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors
+    Key for 64-bit apps: HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
+
+    Add a REG_DWORD value:
+        Name: c:/full/path/to/OpenCLDriverStub.dll
+        Data: 0
+
+    Note: The build_using_cmake.bat builds ICD test as a 32-bit binary.
+    
+2. Run test using ctest.exe
+    cd build
+    ctest.exe
+
+### Cleanup
+
+Manually remove the registry key or .icd files added for running the ICD test.
+
+The "build" and "bin" folders are autogenerated by the build so those may be
+safely deleted without losing any source code (on Linux "make clobber" will
+delete them).
