+# UnliftIO Support for `servant-server`
+
+APIs written in any `MonadUnliftIO m` can be converted to `wai`
+`Application`s without writing the natural transformation by
+hand. These functions will return `m Application` which means that either:
+
+1. You will have to serve from inside your `MonadUnliftIO m` monad, or
+2. You will have to unwrap your application monad to `IO`, bind the
+   `Application`, and then serve it in `IO`.
+
+If you choose the second option, beware `ResourceT` --- trying to use
+the returned `Application` outside of a containing `ResourceT` risks
+attempting to interact with closed resources.
