-Note that `ResultWizard` requires the following LaTeX packages: [`siunitx`](https://ctan.org/pkg/siunitx) and [`ifthen`](https://ctan.org/pkg/ifthen). They are imported in the `results.tex` file via `\usepackage{...}` statements. The package `ifthen` is always presented in a LaTeX distribution. You may have to install the `siunitx` package, which is a widely used package in the scientific community to typeset units, e.g. you can use strings like `\kg\per\cm`.

+in your `ResultWizard` configuration. If the LaTeX document compiles after this, you have an older version of `siunitx` installed. We recommend to upgrade the package to at least version `v3.1.0` to be able to fully customize the output of the result in your LaTeX document via `\sisetup{...}`. See the troubleshooting section down below for more information.

 ## Troubleshooting: LaTeX doesn't build
 
 If your LaTeX document doesn't build, there might be several reasons. Try to find out what's wrong by looking at the log file of your LaTeX compiler (sometimes you have to scroll way up to find the error responsible for the failing build). Also open the `results.tex` file to see if your editor/IDE shows any errors there. You might encounter one of the following errors:
