 If your system Python is not compatible with the required packages, we suggest that you install Python in a Conda environment using the [Micromamba](https://mamba.readthedocs.io/en/latest/user_guide/micromamba.html) package manager for Conda.
 
 - Begin by [installing the Micromamba package manager](https://mamba.readthedocs.io/en/latest/installation/micromamba-installation.html).
-- Install Python 3.8 in a new environment.
+- Install Python 3.11 in a new environment.
 ```
 $ micromamba env create --name ulhpc-docs-python
-$ micromamba install python=3.8 --channel conda-forge --name ulhpc-docs-python
+$ micromamba install python=3.11 --channel conda-forge --name ulhpc-docs-python
 ```
