-  Unikraft has been extensively evaluated in terms of performance. Evaluations of

-  improvement compared to Linux guests.  In addition, Unikraft images for these
-  apps are around 1MB, require less than 10MB of RAM to run, and boot in around
-  1ms on top of the VMM time (total boot time 2ms-40ms).

 ## Overview
+Unikraft allows you to build, at compile time, extremely specialized virtual 
+machines (known as *unikernels*). Unikraft unikernels provide:
 
-Unikraft is a compile-time specialization strategy and alternative system for
-running your application compared to containers or traditional VMs as it allows
-you to completely customize the OS/kernel which facilitates the runtime of your
-application.  There are many benefits in running your application as a
-unikernel: for more information about [the performance
-advantages](/docs/concepts/performance) 🚀, [the added

-environment](/docs/concepts/efficiency) 🌱 please check out the [introductory
-concept chapters](/docs/concepts).
+🚀 High [performance](/docs/concepts/performance) and ultra lightweight deployments.<br />
+🔒 Strong, hardware-level [isolation](/docs/concepts/security) (they're VMs!) and a minimal TCB.<br />
+⚒️ Ease of use, including integration with Dockerfiles and other mainstream [tools](/docs/getting-started/integrations/container-runtimes).<br />
+🤝 Compatibilty with the [Linux API](/docs/concepts/compatibility).<br />
 
 The Unikraft ecosystem consists of an extensive build system and tooling,
 libraries and pre-built unikernel applications.  All of the source code is
