Problem when using Jerome’s Keywords Beta 2.0

I downloaded Jerome’s Keywords, Extracted its contents and transfer them to my web server in a directory called /wp-content/plugins/jeromes-keywords, and then actived it and slected my option at Options / Jerome’s Keywords.

Now, when I writing a post, I can Add tags, but on my blog homepage, no tags were displayed. I know that I have to add some script on some certain pages (or just one), given on “Options / Jerome’s Keywords” page.

Can anyone please tell me where to add Post Tags Display and Cloud tag link format scripts, which page exactly and where?
