+Version 5.4.4
+
+## What is Lua?
+
+Lua is a powerful, efficient, lightweight, embeddable scripting language. 
+It supports procedural programming, object-oriented programming, functional
+programming, data-driven programming, and data description.
+
+Lua combines simple procedural syntax with powerful data description
+constructs based on associative arrays and extensible semantics. Lua is
+dynamically typed, runs by interpreting bytecode with a register-based
+virtual machine, and has automatic memory management with incremental
+garbage collection, making it ideal for configuration, scripting, and
+rapid prototyping. 
+
+## How to use
+
+Clone this repository into `components` subdir of yout project:
+
+```Shell
+cd ~/my_esp_idf_project
+mkdir components
+cd components

+```
+
+Or clone it to any other directory and add it to your project `Makefile` or `CMakeLists.txt`:
+
+```Makefile
+PROJECT_NAME := my-esp-project
+EXTRA_COMPONENT_DIRS := $(HOME)/my/work/path/esp-idf-lua
+include $(IDF_PATH)/make/project.mk
+```
+
+```cmake
+cmake_minimum_required(VERSION 3.5)
+set(EXTRA_COMPONENT_DIRS $ENV{HOME}/my/work/path/esp-idf-lua)
+include($ENV{IDF_PATH}/tools/cmake/project.cmake)
+project(my-esp-project)
