A good usage for this could be, for example, complex navigation on a docs website, where you wouldn't be able to fit it all into the header.

You must put it above the `<main>` content. You can have up to two sidebars per page - the second one will appear on the right side. You can also make a sidebar collapsible by wrapping it's contents in a `<details>` tag - adding the `open` attribute will make it open by default. Here's an example:
