+Before starting the exercise, please download the files [Manifest.toml](Manifest.toml) and [Project.toml](Project.toml), put the files in the same folder that \*.ipynb file is located.
+
+Start Julia in that directory and run the following commands:
+
+```{julia}
+
+using Pkg; Pkg.activate("."); Pkg.instantiate()
+
+```
+
+Now, you are ready to open the notebook in VSCode or alternatively in the same Julia console that you used for installation. You can run the following commands:
+
+```{julia}
+
+using IJulia; notebook(dir=".")
+
+```
