+# Zephyr base project for the LVGL project creator
+
+This repository is used along with LGVL project creator to
+help user to quick setup a Zephyr RTOS application that uses
+LVGL on top of the Zephyr Display subsystem.
+
+## Why this is needed?
+
+Zephyr RTOS already has the LVGL samples but they are
+located inside of the Zephyr kernel source tree, and in general
+the applications are intended to be out from it, the project
+creator helps users with that.
+
+## How to use it:
+
+* Before use the project creator make sure you have zephyr installed on the current folder;
+* After that launch the project creator;
+* After the creation just build the application as regular Zephyr project using `west build`;
