+# Development
+
+_Note: these instructions are only applicable to developers of the SDK itself.  To use the AWS SDK for Swift to access
+various AWS services, follow the instructions in the project's main [README](../README.md)._
+
+You can define a `local.properties` config file at the root of the project to modify build behavior. 
+
+An example config with the various properties is below:
+
+```
+# comma separated list of paths to `includeBuild()`
+# This is useful for local development of smithy-swift in particular 
+compositeProjects=../smithy-swift
+
+# comma separated list of services to exclude from generation from sdk-codegen. When not specified all services are generated
+# specify service.VERSION matching the filenames in the models directory `aws-models -> service.VERSION.json`
+excludeModels=rds-data.2018-08-01, groundstation.2019-05-23 
+
+# comma separated list of services to generate from sdk-codegen. When not specified all services are generated
+# specify service.VERSION matching the filenames in the models directory `aws-models -> service.VERSION.json`.
+onlyIncludeModels=lambda.2015-03-31
+
+# when generating aws services build as a standalong project or not (rootProject = true)
+buildStandaloneSdk=true
+```
+
+**Note:** If a service is specified in both `excludeModels` and `onlyIncludeModels`, it will be excluded from generation. 
+
+
+##### Building a single service
+See the local.properties definition above to specify this in a config file.
+
+```
+>> ./gradlew -PonlyIncludeModels=lambda.2015-03-31  :sdk-codegen:build
+```
+
+##### Testing Locally
+Testing generated services requires `ClientRuntime` of `smithy-swift` and `AWSClientRuntime` Swift packages.

+# Logging
+
+The AWS SDK for Swift uses SwiftLog for high performant logging.  Many of our calls are issued to the `debug` level of output, which are disabled in the console by default.  To see debug output to your console, you can add the following code to your application in a place where you know that the code will be called once and only once:
+```swift
+import ClientRuntime
+SDKLoggingSystem.initialize(logLevel: .debug)
+```
+
+Alternatively, if you need finer grain control of instances of SwiftLog, you can call `SDKLoggingSystem.add` to control specific instances of the log handler.  For example:
+```swift
+import ClientRuntime
+
+SDKLoggingSystem.add(logHandlerFactory: S3ClientLogHandlerFactory(logLevel: .debug))
+SDKLoggingSystem.add(logHandlerFactory: CRTClientEngineLogHandlerFactory(logLevel: .info))
+SDKLoggingSystem.initialize()
+```

+# Stability of the AWS SDK for Swift
+
+For information about maintenance and support of SDK major versions and their underlying dependencies, see the
+following in the AWS SDKs and Tools Shared Configuration and Credentials Reference Guide:
+
+* [AWS SDKs and Tools Maintenance Policy](https://docs.aws.amazon.com/credref/latest/refdocs/maint-policy.html)
+* [AWS SDKs and Tools Version Support Matrix](https://docs.aws.amazon.com/credref/latest/refdocs/version-support-matrix.html)

+## Qualifiers
+
+Qualifiers for published artifacts
+
+**`-alpha`** indicates:
+
+* The SDK is not meant for production workloads. It is released solely for the purpose of getting feedback.
+* The SDK is not yet feature complete. It may contain bugs and performance issues.
+* Expect migration issues as APIs/types change.
+
+**`-beta`** indicates:
+
+* The SDK is not meant for production workloads. 
+* The SDK is feature complete. It may still contain bugs and performance issues.
+* The APIs/types are mostly stabilized. It is still possible that future releases may cause migration issues.
+
+NOTE: This corresponds to the "Developer Preview" phase of the maintenance policy linked above.
