 ## Environments
 
 When you use conda or mamba, you always have an _environment_; the one with which you start is called _base_.  An environment is a "bundle" of a Python version, which need not be the same as your base, along with a set of packages installed against that version.  Only one environment can be active at a time (for Linux users, in a given shell) but environments can be activated and deactivated at will.
