ROOT documentation

ROOT

Folks, is there an easily accessible online ROOT documentation? Right now if I want
to get the description of a class (say, for TH1F), I google this:

then from the results I find one which contains a link to TH1F and eventually end up on my desired destination:

This is incredibly retarded, yet I don’t know of another straightforward way of getting to this page.
Is there a search, where I could type TH1F and come straight upon the documentation?

Is this perhaps a better resource to use? –

Yes, or for specific version of ROOT: root.cern.ch/drupal/content/reference-guide

Cheers,
