-## Backends
+## Integrations
 
-Wherever you can render textured triangles you can use Egui.
+Egui is build to be easy to integrate into any existing game engine or platform you are working on.
+Egui itself doesn't know or care on what OS it is running or how to render things to the screen - that is the job of the egui integration.
+The integration needs to do two things:
+
+* **IO**: Supply Egui with input (mouse position, keyboard presses, ...) and handle Egui output (cursor changes, copy-paste integration, ...).
+* **Painting**: Render the textured triangles that Egui outputs.

-### Writing your own Egui backend
+### Writing your own Egui integration
 
 You need to collect [`egui::RawInput`](https://docs.rs/egui/latest/egui/struct.RawInput.html), paint [`egui::PaintJobs`](https://docs.rs/egui/latest/egui/paint/tessellator/type.PaintJobs.html) and handle [`egui::Output`](https://docs.rs/egui/latest/egui/struct.Output.html). The basic structure is this:
 
 ``` rust
 let mut egui_ctx = egui::Context::new();
 
-// game loop:
+// Game loop:
 loop {
-    let raw_input: egui::RawInput = my_backend.gather_input();

     my_app.ui(&mut ui); // add windows and widgets to `ui` here
     let (output, paint_jobs) = egui_ctx.end_frame();
-    my_backend.paint(paint_jobs);
+    my_integration.paint(paint_jobs);
-    my_backend.set_cursor_icon(output.cursor_icon);
+    my_integration.set_cursor_icon(output.cursor_icon);
     // Also see `egui::Output` for more
 }
 ```
