 # Carbon Decentralized Identifiers
 
-An implementation of the [Decentralized Identifiers (DIDs) v1.0](https://www.w3.org/TR/did-core/) in Java.
+Decentralized Identifiers (DIDs) are a W3C standard for creating and resolving 
+persistent, verifiable identifiers without centralized registries or authorities.  
+They enable secure, portable, and self-sovereign identity for people, 
+organizations, and devices.  
+
+Carbon provides a Java implementation of the 
+[Decentralized Identifiers (DIDs) v1.0](https://www.w3.org/TR/did-core/) 
+specification, making it easier to build and integrate DID-based solutions 
+in Java applications.
+
+The library defines core primitives such as `Did` and `DidUrl` for working with 
+identifiers, together with interfaces for resolving DIDs into DID Documents. 
+These components form the foundation for parsing, constructing, and resolving 
+identifiers in a modular and extensible way, supporting multiple DID methods 
+and resolution strategies.
