and [Cache API](https://developer.mozilla.org/en-US/docs/Web/API/Cache) to allow
your users to access the contents of your site while they are offline or under unreliable
network situations by caching part of your site.

Once you’ve installed this plugin, anyone visiting your site in [browsers that support the Service Workers API](http://caniuse.com/#feat=serviceworkers)
will be able of access your content even if they run out of network or experiment
network instability.

Configure the plugin in the “Settings > Offline content” section of your WordPress
dashboard.

## FAQ

  What browsers support the W3C Service Workers API?

[Browser support for the W3C Service Worker API](http://caniuse.com/#feat=serviceworkers)
currently exists in Firefox, Chrome, and Chrome for Android, with other likely to
follow.

  What is the default policy for caching content?

In a very limited way, yes. You can enable/disable if pages should be precached
