We have examples here, but some of the links seem not good for beginner.

• The stable link is not deployed correctly (e.g. ControlSystems.jl)
• The site is no longer generated by Documenter.jl (e.g. Bio.jl, MergedMethods.jl)
• That package doesn't seem to be actively being developed. (e.g. BanditOpt.jl)
• The site is not generated with latest Documenter.jl (e.g. EvolvingGraphs.jl)
• The package is not registered (e.g. NLOptControl.jl)

Should we remove these links? If so, I'll fix them in #1659.
