 ## Usage
 
-Use an identity & password login:
+Using a Public Agent
 
 ```ts
-import { Tsky } from 'tsky';
-import { CredentialManager } from '@atcute/client';
+import { createAgent } from '@tsky/client';
 
-const manager = new CredentialManager({ service: 'https://bsky.social' });
-await manager.login({
-  identifier: 'alice.tsky.dev',
-  password: 'password',
+const agent = await createAgent({
+  options: {
+    service: 'https://public.api.bsky.app',
+  },
 });
-```
-
-or the [@atcute/oauth-browser-client](https://github.com/mary-ext/atcute/tree/trunk/packages/oauth/browser-client):
-
-```ts
-import { Tsky } from 'tsky';
-import { OAuthUserAgent, finalizeAuthorization } from '@atcute/oauth-browser-client';
-
-// get a session as described at: https://github.com/mary-ext/atcute/tree/trunk/packages/oauth/browser-client
 
-const manager = new OAuthUserAgent(session);
+// Getting a user from their handle
+// First, we need to get the user's DID
+const did = await agent.resolveDIDFromHandle(handle);
+// Then, we can get the user's profile
+const profile = await agent.actor(did);
 ```
 
-and then initialize the tsky client:
+Using an Authenticated Agent
 
 ```ts
-const tsky = new Tsky(manager);
+import { createAgent } from '@tsky/client';
 
-// get the profile of a user
-const profile = await tsky.bsky.profile('did:plc:giohuovwawlijq7jkuysq5dd');
+const agent = await createAgent({
+  credentials: {
+    identifier: "handle",
+      password: "password"
+  }
+});
 
-console.log(profile.handle);
+// Getting the profile of the authenticated user
+const user_profile = await agent.user.profile();
 ```
