 Dioxus SSR can also be to render on the server. Obviously, you can just render the VirtualDOM to a string and send that down.
 
 ```rust
-let text = dioxus_ssr::render_vdom(&vdom, |c| c);
+let text = dioxus::ssr::render_vdom(&vdom, |c| c);
 assert_eq!(text, "<div>hello world!</div>")
 ```
 
 The rest of the space - IE doing this more efficiently, caching the virtualdom, etc, will all need to be a custom implementation for now.
 
+## Usage without a VirtualDom
+
+Dioxus SSR needs an arena to allocate from - whether it be the VirtualDom or a dedicated Bump allocator. To render `rsx!` directly to a string, you'll want to create an `SsrRenderer` and call `render_lazy`.
+
+```rust
+let text = dioxus::ssr::SsrRenderer::new().render_lazy(rsx!{
+    div { "hello world" }
+});
+assert_eq!(text, "<div>hello world!</div>")
+```
+
+This can be automated with the `render_lazy!` macro:
+
+```rust
+let text = render_lazy!(rsx!( div { "hello world" } ));
+```

 ## Usage in static site generation
 
 Dioxus SSR is a powerful tool to generate static sites. Using Dioxus for static site generation _is_ a bit overkill, however. The new documentation generation library, Doxie, is essentially Dioxus SSR on steroids designed for static site generation with client-side hydration.
