I am the only one who will have access to my website.

Just installed my VPS and managed to get most stuff working. However, stuck on the "members" part.

Currently, everything has been done as "root".

I have read posts that I should create a user, because root isn't ideal.

I have found thousand guides on how to create a user, but now what to do next.

1- Should I create a user with adduser username and then add the user to a group? But which group?

2- And will the user then be able to do everything as I have done logged on as "root"?

3- And somebody plz explain what "sudo" has to do with this? (if anything at all)

Thanks
