+OpenMC can be installed in a `conda` environment with `mamba`.
+First, `conda` should be installed with one of the following installers:

+First, add the `conda-forge` channel with:
 
 .. code-block:: sh
 
     conda config --add channels conda-forge
 
+Then create and activate a new conda enviroment called `openmc-env` in

 To list the versions of OpenMC that are available on the `conda-forge` channel,
 in your terminal window or an Anaconda Prompt run:
 
 .. code-block:: sh
 
-    conda search openmc
+    mamba search openmc
 
 OpenMC can then be installed with:
 
 .. code-block:: sh
 
-    conda create -n openmc-env openmc
+    mamba install openmc
 
-This will install OpenMC in a conda environment called `openmc-env`. To activate
-the environment, run:
-
-.. code-block:: sh
-
-    conda activate openmc-env
+You are now in a conda environment called `openmc-env` that has OpenMC installed.
