+### Deploy faasd CE
+
+faasd-ce supports 15 functions and needs a computer with a stable Internet connection to run. There are some restrictions on commercial use, but [individuals and certain small businesses can use it for free](EULA.md).
 
 The easiest way to deploy faasd is with cloud-init, we give several examples below, and post IaaS platforms will accept "user-data" pasted into their UI, or via their API.
