This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun.
Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good.

How to run Ubuntu Snappy Core in Raspberry Pi 2
The Internet of Things (IoT) era is approaching. Soon, in a few years, we will ask ourselves how we were able to survive without the Internet of Things, just as we now suspect that there was no mobile phone in the past. Canonical is a fast-growing but open-market competitor of Iot. The company claims to place its be
