+# Welcome to Workbox
+
+Workbox is a suite of helper libraries for service workers and progressive web
+apps that lets you implement precaching in a manner of minutes. Its features
+support runtime caching, routing, offline analytics, background syncing, and
+more.
+
+## A service worker in two minutes
+
+Use [sw-cli](sw-cli) to add a service worker to an existing project in under two
+minutes. 
+
+## A build script in ten minutes
+
+Generate a service worker in your build process
+using [sw-build](sw-build).
+
+## Much more
+
+Go beyond the basics. If you'd like to use the Workbox libraries, and you
+already have your own service worker, then checkout
+[sw-lib](sw-lib) which lets
+you add to what you've already got.
+
+If you've been using Workbox for a while, or you're
+ambitious, you can delve into its more advanced features. Browse the
+[recipes section](recipes), try the [examples](examples), or look up
+something in the [mobules reference](reference-docs/stable/latest/).
