-## Exporting an interface with `cargo component`
-
-The [sample `add.wit` file](https://github.com/bytecodealliance/component-docs/tree/main/component-model/examples/example-host/add.wit) exports a function. However, you'll often prefer to export an interface, either to comply with an existing specification or to capture a set of functions and types that tend to go together. For example, to implement the following world:
-
-```wit
-package docs:adder@0.1.0;
-
-interface add {
-    add: func(x: u32, y: u32) -> u32;
-}
-
-world adder {
-    export add;
-}
-```
-
-you would write the following Rust code:
-
-```rust
-mod bindings;
-
-// Separating out the interface puts it in a sub-module
-use bindings::exports::docs::adder::add::Guest;
-
-struct Component;
-
-impl Guest for Component {
-    fn add(x: u32, y: u32) -> u32 {
-        x + y
