 If you would also like to install other tools or optional dependencies, it is
 possible to do so by adding additional libraries to this command.  For example::
 
-  mamba create -n asim python=3.9 activitysim jupyterlab larch -c conda-forge --override-channels

 This example installs a specific version of Python, version 3.9.  A similar
 approach can be used to install specific versions of other libraries as well,
