It's pretty self explanatory. I guess some folks are used to everything having warning labels and how-to pictures on em'. I'm baffled by a lot of the posts about Jamba I see. I installed it, and used it. When I wanted to see what a feature did, I tried it. I just looked in my addon folder and of the few that had a 'readme' file, most were donation solicitations or ads for other addons they have written.
