I am not a programmer. I have only used Matlab and VBA for Excel. I installed Conda to begin learning R and Python. Having discovered Julia, I plan to learn R after Julia.
In the documentation I read:
To tell IJulia to use your  own   jupyter  installation, you need to set  ENV["JUPYTER"]  to the path of the  jupyter  program before running  Pkg.add("IJulia")  (if jupyter is in your PATH, you can also just use  ENV["JUPYTER"]="jupyter" ).
I do not know how to set  ENV["JUPYTER"]  to the path of the  jupyter  program.
My PC runs Windows. Should I go the the DOS prompt. And then?
Thanks in advance
