    <dt>How does this work?
    <dd>Each page is cached as a key-value pair in <a href="https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API">IndexedDB</a> (downloaded from a single JSON file).<br>
        The app also uses <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Using_the_application_cache">AppCache</a> and <a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API">localStorage</a> to cache the assets and index files.
    <dt>Can I close the tab/browser?
    <dd>#{canICloseTheTab()}
    <dt>What if I don't update a documentation?
    <dd>You'll see outdated content and some pages will be missing or broken, since the rest of the app (including data for the search and sidebar) uses a different caching mechanism and is updated automatically.<br>
        Documentation versioning is planned for the future but not yet supported, sorry.
    <dt>I found a bug, where do I report it?
    <dd>In the <a href="https://github.com/Thibaut/devdocs/issues">issue tracker</a>. Thanks!
    <dt>How do I uninstall/reset the app?
    <dd>Click <a href="javascript:app.reset()">here</a>.
    <dt>Why aren't all documentations listed above?
    <dd>You have to <a href="#" data-pick-docs>enable</a> them first.
