How can I update the available Android APIs in Eclipse (ADT)

Question

I am trying to update my API level choices within eclipse. Currently, the highest I can get to is API 19:

I am interested in starting with 5.0 and making that my target API, but I cannot seem to get it as an available option.

I have tried updating eclipse via the help -> check for updates, but have seen nothing new.

Currently, I am using the ADT via eclipse (See picture below)

I am sure it is something very simple that I am missing, but can someone tell me where I can find the update to this so that I can start working with things like the glass API, wearables, and Lollipop? Is there a section for updating that I have not seen? Thanks all!
