+### For ESP32 port
+
+Please set `ESPIDF` parameter for the esp-idf install dir.
+It needs to match Micropython expected esp-idf, otherwise a warning will be displayed (and build will probably fail)
+For more details refer to [Setting up the toolchain and ESP-IDF](https://github.com/littlevgl/lv_micropython/blob/master/ports/esp32/README.md#setting-up-the-toolchain-and-esp-idf)
+
+For example:
+`make -C ports/esp32/ ESPIDF=~/esp/projects/lv_mpy_deps/esp-idf`
 
 ## Super Simple Example
 
-Test code to craete a button and a label:
+First, LittlevGL needs to be imported and initialized
+
 ```python
->>> import lvgl
->>> btn = lvgl.btn(lvgl.scr_act())
->>> btn.align(lvgl.scr_act(), lvgl.ALIGN.CENTER, 0, 0)
->>> label = lvgl.label(btn)
->>> label.set_text("Button")
+import lvgl as lv
+lv.init()
+```
+
+Then display driver and input driver needs to be registered.
+Refer to [Porting the library](https://docs.littlevgl.com/#Porting) for more information.
+Here is an example of registering SDL drivers on Micropython unix port:
+
+```python
+import SDL
+
+# Register SDL display driver.
+
+disp_drv = lv.disp_drv_t()
+lv.disp_drv_init(disp_drv)
+disp_drv.disp_flush = SDL.monitor_flush
+disp_drv.disp_fill = SDL.monitor_fill
+disp_drv.disp_map = SDL.monitor_map
+lv.disp_drv_register(disp_drv)
+
+# Regsiter SDL mouse driver
+
+indev_drv = lv.indev_drv_t()
+lv.indev_drv_init(indev_drv) 
+indev_drv.type = lv.INDEV_TYPE.POINTER;
+indev_drv.read = SDL.mouse_read;
+lv.indev_drv_register(indev_drv);
+```
+
+Now you can create the GUI itself
+
+```python
+
+# Create a screen with a button and a label
+
+scr = lv.obj()
+btn = lv.btn(scr)
+btn.align(lv.scr_act(), lv.ALIGN.CENTER, 0, 0)
+label = lv.label(btn)
+label.set_text("Button")
+
+# Load the screen
+
+lv.scr_load(scr)
+
 ```
