-## 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.

-
-`iced_glow` is a [`glow`] renderer for [`iced_native`]. This renderer supports OpenGL 3.0+ and OpenGL ES 2.0.
-
-This renderer is mostly used as a fallback for hardware that doesn't support [`wgpu`] (Vulkan, Metal or DX12).
-
-Currently, `iced_glow` supports the following primitives:
-- Text, which is rendered using [`glow_glyph`]. No shaping at all.
-- Quads or rectangles, with rounded borders and a solid background color.
-- Clip areas, useful to implement scrollables or hide overflowing content.
-- Meshes of triangles, useful to draw geometry freely.

-
-## Installation
-Add `iced_glow` as a dependency in your `Cargo.toml`:
-
-```toml
-iced_glow = "0.8"
-```
-
-__Iced moves fast and the `master` branch can contain breaking changes!__ If
-you want to learn about a specific release, check out [the release list].
-
-[the release list]: https://github.com/iced-rs/iced/releases
-
-## Current limitations
-
-The current implementation is quite naive, it uses:
-
-- A different pipeline/shader for each primitive
-- A very simplistic layer model: every `Clip` primitive will generate new layers
-- _Many_ render passes instead of preparing everything upfront
-- A glyph cache that is trimmed incorrectly when there are multiple layers (a [`glyph_brush`] limitation)
-
-Some of these issues are already being worked on! If you want to help, [get in touch!]

-`iced_glutin` offers some convenient abstractions on top of [`iced_native`] to quickstart development when using [`glutin`].
-
-It exposes a renderer-agnostic `Application` trait that can be implemented and then run with a simple call. The use of this trait is optional. A `conversion` module is provided for users that decide to implement a custom event loop.

-`iced_native` takes [`iced_core`] and builds a native runtime on top of it, featuring:
-- A custom layout engine, greatly inspired by [`druid`]
-- Event handling for all the built-in widgets
-- A renderer-agnostic API
-
-To achieve this, it introduces a bunch of reusable interfaces:
-- A `Widget` trait, which is used to implement new widgets: from layout requirements to event and drawing logic.
-- A bunch of `Renderer` traits, meant to keep the crate renderer-agnostic.
-- A `Windowed` trait, leveraging [`raw-window-handle`], which can be implemented by graphical renderers that target _windows_. Window-based shells (like [`iced_winit`]) can use this trait to stay renderer-agnostic.
