-TODO
+Arm-2D is not a GPU but **an abstraction layer for 2D GPUs dedicated to Microcontrollers**. It supports all Cortex-M processors ranging from Cortex-M0 to the latest Cortex-M85. 
 
+Arm-2D is an open-source project on Github. For more, please refer to: https://github.com/ARM-software/Arm-2D.
+
+
+
+## How to Use
+
+In general, you can set the macro `LV_USE_GPU_ARM2D` to `1`in `lv_conf.h` to enable Arm-2D acceleration for LVGL.
+
+If you are using **[CMSIS-Pack](https://github.com/lvgl/lvgl/tree/master/env_support/cmsis-pack)** to deploy the LVGL. You don't have to define the macro `LV_USE_GPU_ARM2D` manually, instead, please select the component `GPU Arm-2D` in the **RTE** dialog. This step will define the macro for us. 
+
+
+
+## Design Considerations
+
+As mentioned before, Arm-2D is an abstraction layer for 2D GPU; hence if there is no accelerator or dedicated instruction set (such as Helium or ACI) available for Arm-2D, it provides negligible performance boost for LVGL (sometimes worse) for regular Cortex-M processors. 
+
+**We highly recommend you enable Arm-2D acceleration for LVGL** when:
+
+- The target processors are **Cortex-M55** and/or **Cortex-M85**
+- The target processors support **[Helium](https://developer.arm.com/documentation/102102/0103/?lang=en)**.
+- The device vendor provides an arm-2d compliant driver for their propriotory 2D accelerators and/or customized instruction set.
+- The target device contains [DMA-350](https://community.arm.com/arm-community-blogs/b/internet-of-things-blog/posts/arm-corelink-dma-350-next-generation-direct-memory-access-for-endpoint-ai)
