i am new in Pentaho and i use the Pentaho PDI free version for extracting data from Mysql etc...

i would like to use Pentaho dashboard, the free version if exists.
i think i need the CTOOLS.
But in the first link when you say Ctools for Pentaho 5.0 is available (CFD/CDE/CDA/CGG), what do you mean? do i have to download the Pentaho PDI 5.0 ?
Is there a Free version?

I use Windows.

Thank you for your help
