 The library does not implement any specific DID method, but allows DID method implementors to release npm packages that applications can add.
 
-## Breaking changes (0.1.0)
-
-This removes the global resolver. We've learnt that this ended up causing many problems. Instead you should now instantiate a Resolver object and use that to resolve did's within your consuming app/library.
-
-### Changes required for developers of DID resolvers
-
-You now no longer register your DID resolvers using the global `registerMethod()` function. Instead export the resolver function and show how to configure it in a local resolver object.
-
 ## Configure `Resolver` object
 
 You are now required to preconfigure a resolver during instantiation. The `Resolver` constructor expects a registry of methods mapped to a resolver function. For example: 
 ```js
-{ 
+{
   ethr: resolve,
   web: resolve
 }

 ## Implementing a DID method
 
 Each DID method will have its own methods for looking up an identifier on its respective blockchain or other decentralized storage mechanism.
 
-To avoid misconfiguration, method implementers should export a `getResolver()` function which returns an object mapping the method name to a `resolve(did: string, parsed: ParsedDID, didResolver: DIDResolver)` function. e.g. `{ ethr: resolve }`.
