+`egui::Atom` is the new, indivisible building blocks of egui (hence their name).
+An `Atom` is an `enum` that can be either `WidgetText`, `Image`, or `Custom`.
 
-A `egui::Atom` represents the most low-level ui building block in egui. For now this can be `WidgetText` `Image` or `Custom`.
 The new `AtomLayout` can be used within widgets to do basic layout.
 The initial implementation is as minimal as possible, doing just enough to implement what `Button` could do before.
 There is a new `IntoAtoms` trait that works with tuples of `Atom`s. Each atom can be customized with the `AtomExt` trait
 which works on everything that implements `Into<Atom>`, so e.g. `RichText` or `Image`.
 So to create a `Button` with text and image you can now do:
 ```rs
-ui.button((include_image!("my_icon.png").atom_size(Vec2::splat(12.0)), "Click me!"));
+let image = include_image!("my_icon.png").atom_size(Vec2::splat(12.0));
+ui.button((image, "Click me!"));
 ```
 
+Anywhere you see `impl IntoAtoms` you can add any number of images and text, in any order.
+
 As of 0.32, we have ported the `Button`, `Checkbox`, `RadioButton` to use atoms
-(meaning they support adding Atoms and are build on top of `AtomLayout`).
-The `Button` implementation is much simpler now, removing ~130 lines of layout math.
-In combination with `ui.read_response`, custom widgets are really simple now, here is a minimal Button implementation:
