Every broker should show a link to documentation

I am using several of the brokers available and I have to search for the name of each broker on internet to know more about it.

It would be easier if every broker had a link toward the webpage of the broker or some documentation, like what the MARS broker does:

I believe this is done now, but will add it to the Broker Audit (Issue #640 ) as a thing to check for.
