The 3rd paragraph on the page states:

> Our `<.header>` function invocation in the index template doesn’t make use of the `<:subtitle>` slot, so the header/1 function component has nothing to render when it calls `<%= render_slot(@inner_block) %>`.

The `<%= render_slot(@inner_block) %>` in that paragraph should be replaced with `<%= render_slot(@subtitle) %>`

Thanks for pointing that out! We’ll fix that before the final release.
