| Migrating from v0.4.x -> v0.5.0 | |
| Your `Theme` should now have a static `manager` property and this should be used | |
| in place of the global/singleton instance you made and used before. | |
| You no longer need a `themer` property and these should be deleted. | |
| Adding a themeable should now be done via the Theme.manager and looks like this: | |
| ```swift | |
| ExampleTheme.manager.register(themeable: self) | |
| ``` |
