-## Compatibility
-
-All async libraries work with smol out of the box.
-
-The only exception is [tokio], which is traditionally incompatible with [futures] and crashes
-when called from other executors. Fortunately, there are ways around it.
-
-Enable the `tokio02` feature flag and `smol::run()` will create a minimal
-tokio runtime for its libraries:
-
-```toml
-[dependencies]
-smol = { version = "0.3", features = ["tokio02"] }
