On the [README](https://github.com/JuliaLang/juliaup) 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.
