-# Specification 'awesome-semantic-shapes'
+> A curated list of Semantic Shapes resources. Contributions welcome!
+> Please, read the [Contribution Guidelines](CONTRIBUTING.md) first.
 
-This is the repository for awesome-semantic-shapes. You're welcome to contribute! Let's make the Web rock our socks
-off!
+Semantic shapes enable you to validate RDF graphs against a set of conditions.
+Semantic shapes can also be viewed as a description of data graphs that satisfy these conditions.
+Such descriptions may be used for a variety of purposes besides validation,
+including user interface building, code generation, and data integration.
+Semantic shapes are frequently described using the SHACL or ShEx language.
