Hello World, you can find a on google the same title, it is ok
the articles talks about ctrl-p, it is great!
but ctrlp has a problem, when you want explorer or CRUD a directory/file in specific path, ctrlp is not practical.
Dirvis is our complement because you can do all this things and is it like edit a file because you can use 10j or /workspace
In normal mode press - and open your current directory, well, on github you can find all the information, just try it.
