+This is an implementation of Decentralized Identifiers (DIDs) in go. It differs from the alternatives in the following ways:

+- **support producing and using DIDs**: unlike some others, this all-in-one implementation is meant to create, manipulate and handle DIDs
+- **extensible**: you can easily register your custom DID method
