# Installation

If you haven't done so already, download Julia (platform specific instructions can be found here). Next, open the Julia app, which should launch a REPL session, and install IonSim using the following commands:

using Pkg
Pkg.add("IonSim")

The main way you'll want to interact with IonSim is inside of a Jupyter notebook. This requires IJulia.jl:

Pkg.add("IJulia")

And finally, if you'd like to follow along with the example notebooks, you'll need at least PyPlot.jl, an interface to Python's Matplotlib library:

Pkg.add("PyPlot")

Pkg.update("IonSim")
