-## Troubleshooting
-
-### `GraphicsAdapterNotFound`
-
-This occurs when the selected [built-in renderer] is not able to create a context.
-
-Often this will occur while using [`iced_wgpu`] as the renderer without
-supported hardware (needs Vulkan, Metal or DX12). In this case, you could try using the
-[`iced_glow`] renderer:
-
-First, check if it works with
-
-```console
-cargo run --features iced/glow --package game_of_life
-```
-
-and then use it in your project with
-
-```toml
-iced = { version = "0.9", default-features = false, features = ["glow"] }
-```
-
-__NOTE:__ Chances are you have hardware that supports at least OpenGL 2.1 or OpenGL ES 2.0,
-but if you don't, right now there's no software fallback, so it means your hardware
-doesn't support Iced.
