# Alchemy Core
This crate implements the core Alchemy application, which is what users ultimately import. Applications are a singleton; some might not like this, but it enables a design pattern that meshes a bit better with existing GUI framework systems and patterns.
The general pattern for developing with Alchemy is as follows:
``` bash
[Alchemy API] -> [Inner Mutability] -> [Platform Bridge (implemented in other crates)]
|
|
|- [Delegate]
```
The delegate pattern is cribbed from AppKit/UIKit, where it tends to work quite nicely as a way to respond to system level events.
