+# Cmake utilities
+
+[![Component Registry](https://components.espressif.com/components/espressif/cmake_utilities/badge.svg)](https://components.espressif.com/components/espressif/cmake_utilities)
+
+This component is aiming to provide some useful CMake utilities outside of ESP-IDF.
+
+## Use
+
+1. Add dependency of this component in your component or project's idf_component.yml.
+
+    ```yml
+    dependencies:
+      espressif/cmake_utilities: "0.*"
+    ```
+
+2. Include the CMake file you need in your component's CMakeLists.txt after `idf_component_register`, or in your project's CMakeLists.txt
+
+    ```cmake
+    // Note: should remove .cmake postfix when using include(), otherwise the requested file will not found
+    // Note: should place this line after `idf_component_register` function
+    // only include the one you needed.
+    include(package_manager)
+    ```
+
+3. Then you can use the corresponding CMake function which is provided by the CMake file.
