Link to docs in container info

[rugk]

In the container description (info) you have plenty of space for adding some useful things (after the container has been created):

(at least compared to the "advanced" tab)

What I would definitively like to see is some "getting started" guides/links for the container you just cloned. E.g. Firefox could point here: https://wiki.mozilla.org/WebExtensions/Contribution_Onramp

In any case, you can add many helpful things there, so contributors don't have to search, but already know it. 😄
