+# How to use: Copy this file to a cmake modules folder within your project.
+# - Add `list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/your-cmake-modules-folder")`
+# - Call this module by doing `include(AddAzureSDKforC)` from the root CMakeLists.txt.
+# - Link your application against your CMake targets, for example, `target_link_libraries(yourApp PRIVATE az_core)`.
+#
+# This will create a _deps folder for the generated project and Azure SDK will be checked out in there.
+# When calling `cmake --build .`, Azure SDK will be built before your application so it can be available for your app to consume.
+#
+# CMake options for Azure SDK for C can be set together with your application CMake options.
+#
+# Note: Update GIT_TAG to the expected version from Azure SDK for C
