Good resourced to learn to use vim? I want change from atom but every time I try I get frustrated. I only know basic vim.

this one is fun, you have to pay after the first few levels tho

Just start using it and whenever you want to do something Google it and have a cheat sheet handy .

Use it for a few days without switching to another editor. Google everything.
After a week you won't even want to switch anymore.

Worked for me, I still learn new things now and then but the most important stuff can be learned in the first days.

Just write "vimtutor" in terminal and do what the screen says 📺
