+
+In order to run these code snippets we recommend that you download the nix package manager. Nix package manager links from Oktober 2020:
+
+https://nixos.org/download.html
+
+$ curl -L https://nixos.org/nix/install | sh
+
+If you cannot install it using your Wintendo then please consider installing Windows Subsystem for Linux first:
+
+https://docs.microsoft.com/en-us/windows/wsl/install-win10
+
+In order to run the code in this notebook you must enter a sensible working environment. Don't worry! We have created one for you. It's version controlled against python3.7 and you can get the file here:
+
+https://github.com/richardtjornhammar/rixcfgs/blob/master/code/environments/impetuous-shell.nix
+
+Since you have installed Nix as well as WSL, or use a Linux (NixOS) or bsd like system, you should be able to execute the following command in a termnial:
+
+$ nix-shell impetuous-shell.nix
+
+Now you should be able to start your jupyter notebook locally:
+
+$ jupyter-notebook impetuous_finance.ipynb
+
+and that's it.
