+### CLI 💥
+Introducing our new CLI tool!  
+> Make sure you can normally run `make`, `docker compose`, `gcc`, `sh` in your host machine.  
+
+Simply run `make setup` in the root folder to compile & run the CLI tool.  
+
+Don't want to set? Directly go to `Save & Build` menu in it and use `Build and start the server` option to load the app in default settings.  
+
+No gcc compiler? You can choose to compile the file `/setup/setup.c` yourself.
+
+Explore it yourself to find more settings!

 ### Local Machine
 * Please make sure you installed `Node.js` on your local machine.
