The high level steps to use the tools are outlined below:
**1. Define concept sets:** A domain expert defines a list of [concept sets](#defining-concept-sets) for each observable characteristic of the phenotype using CSV file format (e.g., `PHEN_concept_sets.csv`).
**2. Define concept code lists for concept sets:** A domain expert defines [code lists](#defining-concept-codes) for each concept set within the phenotype using supported coding list formats and stores them in the `/src` directory.
