 We strongly recommend installing Topaz into a separate conda environment. To create a conda environment for Topaz:
 ```
-conda create -n topaz python=3.8 (or greater)
+conda create -n topaz python=3.8 (3.8-3.12 are currently supported)
 source activate topaz # this changes to the topaz conda environment, 'conda activate topaz' can be used with anaconda >= 4.4 if properly configured
 # source deactivate # returns to the base conda environment
 ```
