Uninstall previous Julia versions before using JuliaUp

New to Julia

On the README for JuliaUp, it says:

On all platforms it is recommended that you first uninstall any previous Julia versions and undo any modifications you might have made to put julia on the PATH before you install Julia with the installer in this repository.

I understand that currently JuliaUp is the standard way of installing Julia for the first time, but it seems when I first installed Julia I did it another way. I would like to install and start using JuliaUp. Do I just need to uninstall the Julia-X.X.app file or do I also need to delete my ~/.Julia folder as well?

In the .julia folder you mainly find packages. I don’t think it is needed to delete it before installing Julia via juliaup.
The command which julia can tell you if julia is in your search path and where it is installed.

The note on Julia-X-X.app indicates you might be on a Mac?

Then, as Uwe said, keep the .Julia folder, because then you do not have to reinstall any packages. Remove the app and start anew by installing juliaup.
