+#### AWS Bedrock provider usage
+
+The `bedrock` provider enables access to various AI models hosted on AWS Bedrock, including Anthropic Claude, Amazon Titan, Meta Llama, and Mistral models.
+
+**Authentication:**
+
+The Bedrock provider supports two authentication methods:
+
+1. **Bearer Token** (via `AWS_BEDROCK_TOKEN` environment variable):
+   - Use for custom authentication services or proxy scenarios
+   - If set, the provider uses Bearer token authentication and skips AWS Signature v4 signing
+   - Example: `export AWS_BEDROCK_TOKEN="your-token-here"`
+
+2. **Standard AWS Credentials** (default chain):
+   - Environment variables: `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN`
+   - AWS profile: `AWS_PROFILE` environment variable or default profile in `~/.aws/credentials`
+   - IAM role (for EC2/ECS/Lambda environments)
+
+**Configuration:**
+
+Basic configuration:
+
+```yaml
+models:
+  bedrock-claude:
+    provider: bedrock
+    model: anthropic.claude-3-5-sonnet-20241022-v2:0
+    temperature: 0.7
+    max_tokens: 4000
+```
+
+With custom region:
+
+```yaml
+models:
+  bedrock-claude:
+    provider: bedrock
+    model: anthropic.claude-3-5-sonnet-20241022-v2:0
+    provider_opts:
+      region: us-west-2  # Optional, defaults to AWS_REGION or us-east-1
+```
+
+With custom endpoint (for VPC endpoints or proxies):
+
+```yaml
+models:
+  bedrock-claude:
+    provider: bedrock
+    model: anthropic.claude-3-5-sonnet-20241022-v2:0
