+## LVGL Version
+
+This component supports **LVGL8** and **LVGL9**. By default, it selects the latest LVGL version. If you want to use a specific version (e.g. latest LVGL8), you can easily put into `idf_component.yml` in your project like this:
+
+```
+  lvgl/lvgl:
+    version: "^8"
+    public: true
+```
+
+### LVGL Version Compatibility
+
+This component is fully compatible with LVGL version 9. All types and functions are used from LVGL9. Some LVGL9 types are not supported in LVGL8 and there are retyping in [`esp_lvgl_port_compatibility.h`](include/esp_lvgl_port_compatibility.h) header file. **Please, be aware, that some draw and object functions are not compatible between LVGL8 and LVGL9.**
