Cliff Notes version (this is by David Frum so take that into consideration):
What the Mueller Report Actually Said
The special counsel pointed back to the words of his report. Here are its key findings.

....But the words of the report are damning.
The Russian government interfered in the 2016 presidential election in sweeping and systematic fashion, Mueller wrote. This help favored presidential candidate Donald J. Trump and disparaged presidential candidate Hillary Clinton.
The Trump campaign expected it would benefit electorally from information stolen and released through Russian efforts, and it welcomed this help.
There is insufficient evidence to accuse the Trump campaign of criminal conspiracy with its Russian benefactors. However, the social media campaign and the GRU hacking operations coincided with a series of contacts between Trump Campaign officials and individuals with ties to the Russian government.
These contacts were covered up by a series of lies, both to the special counsel and to Congress. Lying by the Trump campaign successfully obscured much of what happened in 2016. The special counsel in some cases was not able to corroborate witness statements through comparison to contemporaneous communications or fully question witnesses about statements that appeared inconsistent with other known facts. In particular, the investigation never did determine what happened to proprietary Trump-campaign polling data shared with the Russians.
Within hours of the appointment of a special counsel to investigate 2016 events, Trump began defaming him. Trump had already fired the FBI director who investigated these events. His first order to fire the special counsel appointed in the directors place was issued on June 17, 2017, a month after Muellers appointment. That order would be followed by many more. Trump directed his staff to lie about these orders.
