<h1>Put header here</h1>

<h3>
You can mount multiple gradio apps on a single FastAPI object for a multi-page app.
However if you mount a gradio app downstream of another gradio app, the downstream
apps will be stuck loading. 
</h3>

<h3>
So in particular if you mount a gradio app at the index route "/", then all your 
other mounted gradio apps will be stuck loading. But don't worry, you can still embed
your downstream gradio apps into the index route using iframes like I do here. In fact,
you probably want to do this anyway since its your index page, which you want to detail 
more fully with a jinja template. 
For a full example, you can see my <a href=https://yfu.one/>generative avatar webapp</a>
