+# Phaistos
+
+The main goal of this project is to provide flexibility and utility in defining data models using YAML manifests,
+to enforce data validation of objects such as ETL pipeline payloads, API requests and responses, configurations and more.
+
+These definitions are to be kept as easily versionable and maintainable files, which can be easily read and understood by
+both developers and non-developers alike.
+
+The main features of Phaistos are:
+
+* Define data models using YAML manifests for easy readability, versioning and maintainability
+* Add custom validators to data fields that are automatically injected into Pydantic models
