WARNING: Some of the informations here apply only if you are using the new iGoogle layout.

To be able to use Rhizosphere in your iGoogle page, first you have to identify a Google Spreadsheet that will contain the data you want to display. Once you have it, follow the instructions about How-To: Use in a Google Spreadsheet to setup the Gadget inside the spreadsheet.

From within the spreadsheet, click the down-facing arrow in the top-right corner of the Rhizosphere Gadget top bar, and choose the option Add Gadget to iGoogle.
That's it. Really easy (thanks Google) !

If you are using the new iGoogle layout (the one with tabs on the left, instead of the top ), you can play with Rhizosphere both in its mini mode or fullscreen mode. More info on How-To: Fullscreen mode
