 Versioning semantic of the binding: `imguiVersion-bindingVersion`.<br>
 For example `1.74-0.1` means that imgui-java uses `1.74` version of Dear ImGui and binding itself has the version `0.1`.

- - [Docking API](#using-docking)

-## Using Docking
+## Using Multi-Viewports and Docking
 Binding based on the Dear ImGui [docking](https://github.com/ocornut/imgui/tree/docking) branch, commit: [90ea7e2f2f3c4096a58b8bd14c274d80ae63e1ce](https://github.com/ocornut/imgui/tree/90ea7e2f2f3c4096a58b8bd14c274d80ae63e1ce).
 That branch contains two important features: [multi-viewports](https://github.com/ocornut/imgui/issues/1542) and [docking](https://github.com/ocornut/imgui/issues/2109).
+See an official documentation about how to work with them.
 
-Even if the viewport feature is still in a very experimental state, yet the docking API seems pretty stable. Thus, imgui-java exposes it and hides everything about viewports.<br>
-See an official documentation about how to work with [docking](https://github.com/ocornut/imgui/issues/2109).
+##### Important!
+Take a note that multi-viewports api is **VERY** complex to implement. It's highly recommended to use `imgui.glfw.ImGuiImplGlfw` class as it's done in the example.
+Otherwise, if you're using your own backed implementation, there are no guarantees it will work.
 
 ## Using FreeType
 Dear ImGui by default uses a stb_strutype library to render a fonts atlas. It's possible to use FreeType instead to get better fonts quality. See an example in [ImGuiGlfwExample](https://github.com/spair/imgui-java/blob/v1.77-0.17.2/imgui-lwjgl3/src/test/java/ImGuiGlfwExample.java).
