 ## AWS Bedrock
 
-We provide support for the [Anthropic Bedrock API](https://aws.amazon.com/bedrock/claude/) through a [separate package](https://github.com/anthropics/anthropic-sdk-typescript/tree/main/packages/bedrock-sdk).
+We provide support for the [Anthropic Bedrock API](https://aws.amazon.com/bedrock/claude/) through a [separate package](https://github.com/anthropics/anthropic-sdk-typescript/tree/main/packages/bedrock-sdk) which reads the [default config](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html).
+
+```ts
+import { AnthropicBedrock } from '@anthropic-ai/bedrock-sdk';
+
+// Note: this assumes you have configured AWS credentials in a way
+// that the AWS Node SDK will recognize, typically a shared `~/.aws/credentials`
+// file or `AWS_ACCESS_KEY_ID` & `AWS_SECRET_ACCESS_KEY` environment variables.
+//

+## Google Vertex
+
+We provide support for the [Google Vertex API](https://cloud.google.com/vertex-ai/generative-ai/docs/partner-models/use-claude) through a [separate package](https://github.com/anthropics/anthropic-sdk-typescript/tree/main/packages/vertex-sdk) which uses [google-auth-library](https://github.com/googleapis/google-auth-library-nodejs) for authentication. `google-auth-library` which by default reads from [Application Default Credentials](https://cloud.google.com/docs/authentication/application-default-credentials) and a number of different authentication methods. If needed you can supply your own `GoogleAuth` instance via the `googleAuth` option.
+
+```ts
+import { AnthropicVertex } from '@anthropic-ai/vertex-sdk';
+
+const client = new AnthropicVertex();
+
+async function main() {
+  const message = await client.messages.create({
+    model: 'claude-3-sonnet@20240229',
+    messages: [
+      {
+        role: 'user',
+        content: 'Hello!',
+      },
+    ],
+    max_tokens: 1024,
