 ====== Edge2 Chromium with WebGL ======
+===== Introduction =====
+This document mainly describes how to install Chromium and add WebGL support.
+<WRAP important >
+If you install Chromium using snap, you can't use WebGL.
+</WRAP>
+<WRAP alert >
+This is just an experienced function, you may got some issues when you enable the WebGL, you can follow the steps below to enable WebGL at your own risk.
+</WRAP>
+===== Upgrade the System =====
+You need to upgrade the system to latest version.
+```shell
+sudo apt update
+sudo apt full-upgrade
+sync
+sudo reboot
+```
+===== Adjust GPU Links =====
+In order to use the WebGL you need to adjust the GPU links, you can follow the steps below:
+```shell
+sudo cp /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0 /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0.backup
+sudo ln -fs /usr/lib/aarch64-linux-gnu/libMali.so /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0
+sync
+```
+<WRAP alert >
+These steps will break the X11 desktop, if you want to use the X11 desktop, you can follow the tetps below to recovery to original state.
+```shell

+===== Install Chromium from APT Source =====
+Ubuntu 22.04 will use ''snap'' to install software by default, in order to add WebGL support we need to install Chromium from other apt source.
+```shell

+sudo apt remove chromium-browser
+sudo snap remove chromium
+sudo apt install chromium-browser
+```
