+# Raw Sync Lambda
+
+The raw sync Lambda ensures that the input and raw S3 buckets are synchronized
+by verifying that all non-zero sized JSON in each export in the input bucket
+have a corresponding object in the raw bucket.
+
+If a JSON file from an export is found to not have a corresponding object in the raw bucket,
+the file is submitted to the raw Lambda (via the dispatch SNS topic) for processing.
+
+## Development
+
+The Serverless Application Model Command Line Interface (SAM CLI) is an
+extension of the AWS CLI that adds functionality for building and testing
+Lambda applications.
+
+To use the SAM CLI, you need the following tools.
+
+* SAM CLI - [Install the SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html)
+* Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community)
+
+You may need the following for local testing.
+* [Python 3 installed](https://www.python.org/downloads/)
+
+You will also need to configure your AWS credentials, if you have not already done so.
+
+## Creating a local build
+
+Use the SAM CLI to build and test your lambda locally.
+Build your application with the `sam build` command.
+
+```bash
+cd src/lambda_function/raw_sync/
+sam build
+```
+
+## Tests
+
+Tests are available in `tests/test_lambda_raw_sync.py`.
