+### CORS Configuration
+
+CORS (Cross-Origin Resource Sharing) can be configured in two ways:
+
+**Local development** (allows localhost origins only):
+```yaml
+server:
+  cors: true
+```
+
+**Explicit configuration** (custom origins and settings):
+```yaml
+server:
+  cors:
+    allow_origins: ["https://myapp.com", "https://app.example.com"]
+    allow_methods: ["GET", "POST", "PUT", "DELETE"]
+    allow_headers: ["Content-Type", "Authorization"]
+    allow_credentials: true
+    max_age: 3600
+```
+
+When `cors: true`, the server enables secure localhost-only access for local development. For production, specify exact origins to maintain security.
+
 ### Authentication Configuration
 
 > **Breaking Change (v0.2.14)**: The authentication configuration structure has changed. The previous format with `provider_type` and `config` fields has been replaced with a unified `provider_config` field that includes the `type` field. Update your configuration files accordingly.
@@ -618,6 +642,54 @@ Content-Type: application/json

 ```
 
+### CORS Configuration
+
+Configure CORS to allow web browsers to make requests from different domains. Disabled by default.
+
+#### Quick Setup
+
+For development, use the simple boolean flag:
+
+```yaml
+server:
+  cors: true  # Auto-enables localhost with any port
+```
+
+This automatically allows `http://localhost:*` and `https://localhost:*` with secure defaults.
+
+#### Custom Configuration
+
+For specific origins and full control:
+
+```yaml
+server:
+  cors:
+    allow_origins: ["https://myapp.com", "https://staging.myapp.com"]
+    allow_credentials: true
+    allow_methods: ["GET", "POST", "PUT", "DELETE"]
+    allow_headers: ["Content-Type", "Authorization"]
+    allow_origin_regex: "https://.*\\.example\\.com"  # Optional regex pattern
+    expose_headers: ["X-Total-Count"]
+    max_age: 86400
+```
+
+#### Configuration Options
+
+| Field                | Description                                    | Default |
+| -------------------- | ---------------------------------------------- | ------- |
+| `allow_origins`      | List of allowed origins. Use `["*"]` for any. | `["*"]` |
+| `allow_origin_regex` | Regex pattern for allowed origins (optional). | `None`  |
+| `allow_methods`      | Allowed HTTP methods.                          | `["*"]` |
+| `allow_headers`      | Allowed headers.                               | `["*"]` |
+| `allow_credentials`  | Allow credentials (cookies, auth headers).    | `false` |
+| `expose_headers`     | Headers exposed to browser.                   | `[]`    |
+| `max_age`            | Preflight cache time (seconds).               | `600`   |
+
+**Security Notes**:
+- `allow_credentials: true` requires explicit origins (no wildcards)
+- `cors: true` enables localhost access only (secure for development)
+- For public APIs, always specify exact allowed origins
+

 Configuring Safety can be a little involved so it is instructive to go through an example.

+# S3 Files Provider
+
+A remote S3-based implementation of the Llama Stack Files API that provides scalable cloud file storage with metadata persistence.
+
+## Features
+
+- **AWS S3 Storage**: Store files in AWS S3 buckets for scalable, durable storage
+- **Metadata Management**: Uses SQL database for efficient file metadata queries
+- **OpenAI API Compatibility**: Full compatibility with OpenAI Files API endpoints
+- **Flexible Authentication**: Support for IAM roles and access keys
+- **Custom S3 Endpoints**: Support for MinIO and other S3-compatible services
+
+## Configuration
+
+### Basic Configuration
+
+```yaml
+api: files
+provider_type: remote::s3
+config:
+  bucket_name: my-llama-stack-files
+  region: us-east-1
+  metadata_store:
+    type: sqlite
+    db_path: ./s3_files_metadata.db
+```
+
+### Advanced Configuration
+
+```yaml
+api: files
+provider_type: remote::s3
+config:
+  bucket_name: my-llama-stack-files
+  region: us-east-1
+  aws_access_key_id: YOUR_ACCESS_KEY
+  aws_secret_access_key: YOUR_SECRET_KEY
+  endpoint_url: https://s3.amazonaws.com  # Optional for custom endpoints
+  metadata_store:
+    type: sqlite
+    db_path: ./s3_files_metadata.db
+```
+
+### Environment Variables
+
+The configuration supports environment variable substitution:
+
+```yaml
+config:
+  bucket_name: "${env.S3_BUCKET_NAME}"
+  region: "${env.AWS_REGION:=us-east-1}"
+  aws_access_key_id: "${env.AWS_ACCESS_KEY_ID:=}"
+  aws_secret_access_key: "${env.AWS_SECRET_ACCESS_KEY:=}"
+  endpoint_url: "${env.S3_ENDPOINT_URL:=}"
+```
+
+Note: `S3_BUCKET_NAME` has no default value since S3 bucket names must be globally unique.
+
+## Authentication
+
+### IAM Roles (Recommended)
+
+For production deployments, use IAM roles:
+
+```yaml
+config:
+  bucket_name: my-bucket
+  region: us-east-1
+  # No credentials needed - will use IAM role
+```
+
+### Access Keys
+
+For development or specific use cases:
+
+```yaml
+config:
+  bucket_name: my-bucket
+  region: us-east-1
+  aws_access_key_id: AKIAIOSFODNN7EXAMPLE
+  aws_secret_access_key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
+```
+
+## S3 Bucket Setup
+
+### Required Permissions
+
+The S3 provider requires the following permissions:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "s3:GetObject",
+        "s3:PutObject",
+        "s3:DeleteObject",
+        "s3:ListBucket"
+      ],
+      "Resource": [
+        "arn:aws:s3:::your-bucket-name",
+        "arn:aws:s3:::your-bucket-name/*"
+      ]
+    }
+  ]
+}
+```
+
+### Automatic Bucket Creation
+
+By default, the S3 provider expects the bucket to already exist. If you want the provider to automatically create the bucket when it doesn't exist, set `auto_create_bucket: true` in your configuration:
+
+```yaml
+config:
+  bucket_name: my-bucket
+  auto_create_bucket: true  # Will create bucket if it doesn't exist
+  region: us-east-1
+```
+
+**Note**: When `auto_create_bucket` is enabled, the provider will need additional permissions:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "s3:GetObject",
+        "s3:PutObject",
+        "s3:DeleteObject",
+        "s3:ListBucket",
+        "s3:CreateBucket"
+      ],
+      "Resource": [
+        "arn:aws:s3:::your-bucket-name",
+        "arn:aws:s3:::your-bucket-name/*"
+      ]
+    }
+  ]
+}
+```
+
+### Bucket Policy (Optional)
+
+For additional security, you can add a bucket policy:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Sid": "LlamaStackAccess",
+      "Effect": "Allow",
+      "Principal": {
+        "AWS": "arn:aws:iam::YOUR-ACCOUNT:role/LlamaStackRole"
+      },
+      "Action": [
+        "s3:GetObject",
+        "s3:PutObject",
+        "s3:DeleteObject"
+      ],
+      "Resource": "arn:aws:s3:::your-bucket-name/*"
+    },
+    {
+      "Sid": "LlamaStackBucketAccess",
+      "Effect": "Allow",
+      "Principal": {
+        "AWS": "arn:aws:iam::YOUR-ACCOUNT:role/LlamaStackRole"
+      },
+      "Action": [
+        "s3:ListBucket"
+      ],
+      "Resource": "arn:aws:s3:::your-bucket-name"
+    }
+  ]
+}
+```
+
+## Features
+
+### Metadata Persistence
+
+File metadata is stored in a SQL database for fast queries and OpenAI API compatibility. The metadata includes:
+
+- File ID
+- Original filename
+- Purpose (assistants, batch, etc.)
+- File size in bytes
+- Created and expiration timestamps
+
+### TTL and Cleanup
+
+Files currently have a fixed long expiration time (100 years).
+
+## Development and Testing
+
+### Using MinIO
+
+For self-hosted S3-compatible storage:
+
+```yaml
+config:
+  bucket_name: test-bucket
+  region: us-east-1
+  endpoint_url: http://localhost:9000
+  aws_access_key_id: minioadmin
+  aws_secret_access_key: minioadmin
+```
+
+## Monitoring and Logging
+
+The provider logs important operations and errors. For production deployments, consider:
+
+- CloudWatch monitoring for S3 operations
+- Custom metrics for file upload/download rates
+- Error rate monitoring
+- Performance metrics tracking
+
+## Error Handling
+
+The provider handles various error scenarios:
+
+- S3 connectivity issues
+- Bucket access permissions
+- File not found errors
+- Metadata consistency checks
+
+## Known Limitations
+
+- Fixed long TTL (100 years) instead of configurable expiration
+- No server-side encryption enabled by default
+- No support for AWS session tokens
+- No S3 key prefix organization support
+- No multipart upload support (all files uploaded as single objects)
