 ## Usage
 
-TBD
+The library exports two main things: a global `registryCollection`, containing 
+an instance of registry collections, and a loading function.
+
+```js
+import { registryCollections, loadRegistryCollections } from '@digitalcredentials/issuer-registry-client'
+
+// registryCollections is empty, when first exported
+
+// Load the registries from the web (typically done at app startup).
+await loadRegistryCollections()
+
+// You can now query to see if a given DID is in a registry
+isInRegistryCollection('did:example:123')
+// false
+```
