 **Important**: *Before installing CFizer*, update the configuration file, `cfizer/config.yml` and, if necessary, the vocabulary (`cfizer/vocabulary.yml`) - see [Setup](#setup) below. Installation creates a copy of these in the virtual environment, so any subsequent changes either need to be made to the version in that environment, or require re-installation.

 # Setup
 The most important setup for users is to check/complete the `cfizer/vocabulary.yml` and `cfizer/config.yml` files. They define, respectively, how the MONC variables are to be modified for CF compliance, and parameters that should be uniform across a set of files, including the source of the original data.
