+# Developer Guide
+
+## Prerequisites
+
+The .NET 6.0 SDK is required:
+
+```
+$ dotnet --list-sdks
+6.0.xxx
+```
+
+## Running Tests
+
+The integration tests will download opensearch and run a local cluster for you. To run the full suite of tests, all you need to do is call the below script.
+
+```
+.\build.bat
+```
+
+```
+build.sh
+```
+
+## Client Code Generator
+
+OpenSearch publishes an [OpenAPI specification](https://github.com/opensearch-project/opensearch-api-specification/releases/download/main/opensearch-openapi.yaml) in the [opensearch-api-specification](https://github.com/opensearch-project/opensearch-api-specification) repository, which is used to auto-generate the less interesting parts of the client.
+
+```
+./build.sh codegen --branch main
+```
+or
+```
+./build.bat codegen --branch main
+```
