1. Navigate to your iGoogle page, and click on Add Stuff button
2. type "delicious" into search for gadgets search tool
3. I chose "Del.icio.us bookmarks" from search results.
4. return to igoogle page where you will see the delicious feed
5. click on "edit settings" from the delicious feed
6. configure by setting your username, Display "all links", and typing your tag(s)
7. save settings
