+An implementation of JSON Schema for Python.
+
+The main functionality is provided by the validator classes for each of the
+supported JSON Schema versions.
+
+Most commonly, `jsonschema.validators.validate` is the quickest way to simply
+validate a given instance under a schema, and will create a validator
+for you.
