+## Introduction
+
+The **commonlibrary** subsystem provides common enhanced APIs for development in C, C++ and JS.
+
+**c_utils**
+
+- Enhanced APIs for operations related to files, paths, and strings
+- APIs related to the read-write lock, semaphore, timer, thread, and thread pool
+- APIs related to the security data container and data serialization
+- Error codes for each subsystem
+- Safe functions in C
+
+**ets_utils**
+
+- JSAPIs for operation of URI, URL and xml
+- JSAPIs for character encoder and decoder
+- JSAPIs for operation of process
+- Multithreading ability in JS
+
+**utils_lite**
+
+- Hardware Abstraction Layer (HAL) APIs for performing operations on standard files
+- APIs for internal functions, such as the timer
