 Iced was originally born as an attempt at bringing the simplicity of [Elm] and
 [The Elm Architecture] into [Coffee], a 2D game engine I am working on.
 
-Currently, Iced builds upon
-  * [`stretch`] for flexbox-based layouting.
+The core of the library was implemented during May in [this pull request], using
+[`stretch`] for flexbox-based layouting. It was later released as the main
+feature of [Coffee 0.3.0].
+
+After release, different folks asked if the GUI could be split into a standalone
+crate, and well... Iced is here!
+
+As an interesting note, Iced does not rely on reference counting and interior
+mutability at all! There is not a single `Rc`, `RefCell`, or similar used
+directly in the library.
