+## Installation
+
+Tested are Python 3.11, PySide2 5.15.11 and Qt 5.15.11. The later two are necessary for the visualisation. Install all Python requirements by using
+
+```sh
+pipenv --site-packages sync
+```
+
+### Caveats
+
+Only the most recent version of pyside2 is compatible with Python 3.11. Unfortunately the version cannot be found on the Python Package Index and may have to be installed manually and allowing system site-packages in the pipenv.
+For this, run the following before any virtual environment exists (or remove the existing virtual environment using `pipenv --rm`):
+
+```sh
+pipenv --site-packages sync
+```
+
+
+## Fetch Recipes
+
 Using pipenv, run e.g.
 
 ```sh
 pipenv run fetch --result 'Molten Iron'
 ```
