 In [`Jetpack Compose`](https://developer.android.com/jetpack/compose), we use something called [`Previews`](https://developer.android.com/jetpack/compose/tooling), which are `Composable` functions written specifically to preview (or interact with) the UI rendered by `Compose` in the editor itself without needing to run the app on a device.

 ## 5. How do I use `Dowel`?
 There are only 3 `Dowel` annotations you need to know about:
-1. [`@Dowel`](https://github.com/JayaSuryaT/Dowel/blob/main/dowel-annotation/src/main/java/com/jayasuryat/dowel/annotation/Dowel.kt) : The primary entry point into `Dowel`, triggeres generation `PreviewParameterProvider` for that class.

 2. [`@DowelList`](https://github.com/JayaSuryaT/Dowel/blob/main/dowel-annotation/src/main/java/com/jayasuryat/dowel/annotation/DowelList.kt) : Same as `@Dowel`, but generates a `PreviewParameterProvider` of type `List<T>` where `T` is the class annotated with `@DowelList` annotation. Rest of the behavior is same as the `@Dowel` annotation.
 3. [`@ConsiderForDowel`](https://github.com/JayaSuryaT/Dowel/blob/main/dowel-annotation/src/main/java/com/jayasuryat/dowel/annotation/ConsiderForDowel.kt) : If you want to add support for an unsupported type, or override provider logic for a particular type, then you can do that with `@ConsiderForDowel` annotation.
