+In this document we give a high level technical overview of CloudFleet. Using
+CloudFleet consists of three main components:
+
+- the Blimp hardware - a physical machine used as your Blimp
+- the Blimp software - the open source software running on your Blimp
+- CloudFleet services - a set of online services we provide to make the setup
+and usage of your Blimp easy and safe
+
+You can get a pre-packaged CloudFleet Blimp from us or you can install the Blimp
+on your own hardware or VM.
 
 ## Hardware
 
-Raspberry Pi 2 Model B. Specification:
+Hardware changes fast, so it's possible that these specs might change soon,
+but this is the current hardware overview.
+The main hardware platform supported for our Blimp is a Raspberry Pi 2 Model B.
+The machine's specification is:
 
 - 900MHz quad-core ARM Cortex-A7 CPU
 - 1GB RAM
 
-Additional components
+Additional components that we package with the Blimp are:
 
 - Custom case with CloudFleet branding
 - 8 GB boot Micro SD card
 - 16 GB storage USB
 - Encryption USB key
 - Ethernet & power cables
 
+We also test our software on Debian amd64 VMs, we have some Solidrun Cuboxes
+that mostly work and we are open to patches if
+you would like to add support for some other hardware platforms.
