I’m 100% sure I want Gazebo. I go to the main website and am encouraged to “Get Started”. I do, and am directed to https://gazebosim.org/docs/all/getstarted which immediately starts talking about “Ignition”, not Gazebo. But there is a (potentially) helpful invitation to read an overview if you are not quite sure what “Ignition” is about… that leads to a completely blank and useless page.
I hope this is not an indication of the quality of documentation I should expect from Gazebo.
