+1. Install tools 
+
+   ```sh
+   $ sudo apt install clang git make ninja-build
+   $ sudo apt install lib{opengl-dev,gl1-mesa-dev,glfw3,glfw3-dev,xcursor-dev,xinerama-dev,xi-dev}
+   $ sudo apt install libsdl2-dev libsdl3-dev
+   ```
+
+1. Download files,

+      ```
+
+1. Generate imgui.so
+   
+   ```sh
+   $ cd ruby-imgui-dev/imgui_dll
+   $ make
+   ```
+
+   `imgui.so` file is generated in `ruby-imgui-dev/lib`
