vim autoformat ?

I can't wrap my head around Vim autoformat at all. 

I want to have autoformat on save feature. 

I don't want it to have delays, so when i press `:w` it immediatelly saves and formats indentation properly.

I have no idea what is going on in (neo)Vim discussions about this autoformating. Looks like those people never coded in their life, and never do any useful thing with their godly configs other than to brag.

Using Vim feature `gg=G` i format and indent whole file. 

This is what I want to have, but discussions related to this are so complicated. They just say 'look at my config', but I have no idea, what is that I should look into his config, or just copying his whole config with a lot of bloat. 

Please help.
