# SNOMED CT Concept Editor

The Concept Editor serves two basic functions:

* You can view detailed information about a concept and its various associated components (e.g. descriptions, relationships, and Reference Set members).
* You can make changes to a concept (e.g. adding another clinical phrase to describe the concept, retiring a concept or description).
