Meteohub/Weatherhub setup to work with WD

We have Linux Mint 10.10, and downloaded Weather Display, which was recently registered. How do we set it up to grab data from our Meteohub/Weatherhub? We found a set of instructions online that related to a windows version, and started going through it, before realizing the options on version 10.37 L were quite different. Help would be appreciated.
