-The Wasmer Universal engine is usable with any compiler implementation based
-on [`wasmer-compiler`]. After the compiler process the result, the Universal
-pushes it into memory and links its contents so it can be usable by
-the [`wasmer`] API.
-
-*Note: you can find a [full working example using the Universal engine
-here][example].*
