 1. The easiest way for any user to install CNApy is by downloading its installer, which is provided for Windows, Linux and MacOS, see [Using CNApy installer](#using-cnapy-installer) for more.
 2. If you already have installed Python 3.10 (no other version) on your system, you can install CNApy simply through ```pip install cnapy``` in your console. Afterwards, you can start CNApy's GUI by running either ```cnapy``` or, if this doesn't work, ```python -m cnapy``` where "python" must call your Python 3.10 installation.
-3. If you already use conda or mamba (for mamba, just change the "conda" command to "mamba"), you can create a CNApy environment named ```cnapy-1.2.2``` as follows: 1) Run ```conda create --name cnapy-1.2.2 python=3.10 pip openjdk -c conda-forge```, 2) run ```conda activate cnapy-1.2.2```, 3) run ```pip install cnapy```. Then, you can start CNApy in the cnapy-1.2.2 conda environment by running either ```cnapy``` or, if this doesn't work, ```python -m cnapy```. Note that the [cnapy conda package](https://anaconda.org/cnapy/cnapy) is currently *not* being updated due to licensing uncertainties.
+3. If you already use conda or mamba (for mamba, just change the "conda" command to "mamba"), you can create a CNApy environment named ```cnapy-1.2.3``` as follows: 1) Run ```conda create --name cnapy-1.2.3 python=3.10 pip openjdk -c conda-forge```, 2) run ```conda activate cnapy-1.2.3```, 3) run ```pip install cnapy```. Then, you can start CNApy in the cnapy-1.2.3 conda environment by running either ```cnapy``` or, if this doesn't work, ```python -m cnapy```. Note that the [cnapy conda package](https://anaconda.org/cnapy/cnapy) is currently *not* being updated due to licensing uncertainties.
