Someone recommended me that I should use `vimtutor` to learn the basics of `vim`. But I have no idea how to use it. Is it an application? A website?

[This is the only link](https://web.archive.org/web/20100107121743/http://linuxcommand.gds.tuwien.ac.at/man_pages/vimtutor1.html) that was given during the discussion here and I can't find a link to anything.

Any suggestions?
