## 404

This page doesn't exist. The site's real pages are linked from the
nav: [home]({{ '/' | relative_url }}) ·
[documentation]({{ '/documentation' | relative_url }}) ·
[building]({{ '/building' | relative_url }}).

*Note for anyone following a moved link: the old "under the hood" page now
lives at [documentation]({{ '/documentation' | relative_url }}).*

<!-- Links use the | relative_url filter on purpose: a 404 page is served for
     ANY unknown path, so plain relative links would resolve against the
     requested (dead) URL instead of the site root. -->
