The Jupyter notebooks can be viewed directly at GitHub ([example](https://github.com/PTsolvers/PseudoTransientStokes.jl/blob/main/dispersion_analysis/dispersion_analysis_stokes1D.ipynb)). However, in order to view the notebook on a local computer or to make changes to the scripts, the recent Python installation is required. Also, several Python packages need to be installed: SymPy, NumPy, Jupyter, and Matplotlib. The easiest way to install these packages along with their dependencies is to use the [Anaconda](https://www.anaconda.com/products/individual) platform.
