Here is a better summary from a former federal prosecutor:
You missed probably the most important parts of the indictment as they relate to Trump. The main findings are:
1) Stone got damaging emails from Wikileaks at the direction of a 'senior Trump campaign official' in order to help Trump's campaign.
2) This senior official (or another senior official) was directed by someone above them (likely Trump, Trump Jr., or Kushner) to have Stone find out what other damaging materials Wikileaks might provide them with, the DNC's hacked emails in particular.
3) Stone then lied to Congress about this.
4) Stone then encouraged other people to lie to Congress about this in order to keep their stories straight.
