Cumulus Support

Morning Guys n Gals.

Firstly my name is Tristen, "Hi There". Im a Volunteer Crewman at my local RNLI (Lifeboat) station.
We have been donated a Weather station (Davis Advantage Pro2) with USB Datalogger.

We would like to use a RPi (2?) to run CumulusMX to display the information on our website. Having looked around the internet, it looks like it has been successfully done many times. But as none of us have experience with the RPi, I wonder if anyone knows of, or has, a "Step by Step for Dummies" Guide?

Any help would be gratefully recieved

The Raspberry Pi site has guides on getting started with a Pi. Once you have the Pi running, and have familiarised yourself with its basic operation via the command line, it is very easy to install and run MX - the step by step instructions are in the original announcement.
