Download and install Julia following the instructions here: https://julialang.org/downloads/

The Julia version used in demo is 1.11.7 (stable release Sept 2025). To update Julia, use juliaup update on the command line.

Start the Julia enviroment with julia on the command line. This should bring you to a prompt that looks like this:

Try it out! Simple calculations like 3+5 will already work.

Note: Julia syntax stays surprisingly close to basic calculus. For instance, you can define a simple function using something like f(x,y) = x + y . Then, you can execute it immediately with f(3,2). If there is a simple calculation you need often, this is a great way to do it.

Clone this repository locally (or download the files) and navigate to it in your command line. Start julia from this directory.

To start a Pluto notebook, we first need to import (activate) the Package manager and add Pluto:

import Pkg; Pkg.add(\"Pluto\")

Note: Alternatively, use the ] command to go into the very useful Pkg command line and then use add Pluto for the same end result. Use backspace or Ctrl +C to exit the Pkg command line.

Note: Adding a package (and some other operations) often trigger a compilation phase. This is typical Julia behaviour and gets faster as it starts caching the packages.

Import the Pluto backend by running import Pluto (only needed once per Julia session).

Pluto.run() starts the backend. This will (should) open a browser window.

Note: Pluto uses its own package management system. Whatever you import on the Julia command line is not carried over into your notebooks.

Use the Pluto interface (should have opened a webpage in your webbrowser) to open carbon_notebook.jl.

Use the Run notebook code button top right in the browser window to execute the code.

Adapt the code as you like.

Close Pluto with Ctrl+C in the Julia command line.

Close Julia with the function exit() or Ctrl+C.
