  # Universal Resolver
  
  A Universal Resolver is an identifier resolver that works with any decentralized identifier system, including Decentralized Identifiers (DIDs).
  
  See this [blog post](https://medium.com/decentralized-identity/a-universal-resolver-for-self-sovereign-identifiers-48e6b4a5cc3c) and this [webinar](https://ssimeetup.org/did-resolution-given-did-how-do-retrieve-document-markus-sabadello-webinar-13/) for an introduction.
  
  See https://resolver.identity.foundation/ for a stable version or https://dev.uniresolver.io/ for a test instance of a Universal Resolver.
  
  ## Quick Start
  
  You can deploy the Universal Resolver on your local machine by cloning this Github repository, and using `docker-compose` to build and run the Universal Resolver as well as its drivers.
  
  	git clone https://github.com/decentralized-identity/universal-resolver
  	cd universal-resolver/
  	docker-compose -f docker-compose.yml pull
  	docker-compose -f docker-compose.yml up
  
  You should then be able to resolve identifiers locally using simple `curl` requests as follows:
  
  	curl -X GET http://localhost:8080/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw
