+#### Using the nix package manager
+Blitz API provides a [Nix](https://github.com/NixOS/nix) Flake file to create a development environment. Execute `nix develop` (make sure you have flakes enabled) to enter the environment.
+
+In this environment a hidden folder `.venv` is created to install the python dependencies locally. If pyright can't find these dependencies create the following file in the root
+folder of the project:
+```json
+{
+  "venvPath": ".",
+  "venv": ".venv"
+}
+```
