+`check-datapackage` is a Python package that checks your Data Package's
+metadata against the [Data Package standard](https://datapackage.org/),
+helping you ensure that your metadata is compliant.
+
+## Key features :sparkles:
+
+-   Checks the
+    [descriptor](https://datapackage.org/standard/glossary/#descriptor)
+    in your `datapackage.json` against the Data Package standard.
+-   Enables you to configure which components of the descriptor
+    should or should not be checked.
+-   Enables you to turn off specific checks defined in the standard.
+-   Supports user-defined, custom checks.
+-   Provides clear and user-friendly messages that point directly to
+    where issues occur in the descriptor.
+-   Supports a strict mode that enforces full compliance with the
+    standard, including all recommendations.
+
+:warning: Note that `check-datapackage` only checks the descriptor
+against the Data Package standard---it does not check the data itself
+against its descriptor.
