You are spreading disinformation. The FBI investigations into Russia collusion were separate from Mueller's special counsel investigations, Mueller's work did not refer to the Steele Dossier at all.

Mueller's key findings include

- Uncovering extensive criminal activity on the part of Trump associates

- that Russia engaged in extensive attacks on the US election system in 2016

- that there were numerous links between the Russian government and the Trump campaign

- that there were multiple episodes in which Trump engaged in deliberate obstruction during the investigation

If you are taking Trump's "no collusion, complete exoneration" at his word, understand that he was lying. The report literally used the phrase "does not exonerate", and the only reason Trump was not indicted was because of the DOJ policy that you can't indict a sitting president.
