 ### Migrating
 
-[Kingfisher 6.0 Migration](https://github.com/onevcat/Kingfisher/wiki/Kingfisher-6.0-Migration-Guide) - Kingfisher 6.x is NOT fully compatible with the previous version. However, the migration is not difficult. Depending on your use cases, it may take no effect or several minutes to modify your existing code for the new version. Please follow the [migration guide](https://github.com/onevcat/Kingfisher/wiki/Kingfisher-6.0-Migration-Guide) when you prepare to upgrade Kingfisher in your project.

 > - Kingfisher 4.0 Migration - Kingfisher 3.x should be source compatible to Kingfisher 4. The reason for a major update is that we need to specify the Swift version explicitly for Xcode. All deprecated methods in Kingfisher 3 were removed, so please ensure you have no warning left before you migrate from Kingfisher 3 to Kingfisher 4. If you have any trouble when migrating, please open an issue to discuss.
