+There are three variants of the example project:
+- [bifunctor-tagless][bifunctor-tagless](bifunctor-tagless) – Main example. It's written in bifunctor tagless final style with [BIO](https://izumi.7mind.io/bio/) typeclasses, uses [ZIO](https://zio.dev) as a runtime and ZIO Environment for composing test fixtures.
 - [monofunctor-tagless](monofunctor-tagless) – Written in monofunctor tagless final style with [Cats Effect](https://typelevel.org/cats-effect/) typeclasses, and can run using both [Cats IO](https://typelevel.org/cats-effect/) and [ZIO](https://zio.dev) runtimes.
 - [monomorphic-cats](monomorphic-cats) – A simpler example written without tagless final, uses [Cats IO]() directly everywhere.
