+# AWS-SDK-SQS
+
+This project builds a Dafny SDK for [AWS SQS](https://aws.amazon.com/sqs/).
+It is a copy of the `TestModels/aws-sdks/sqs` project,
+but it generates code using the older CLI instead of the newer Smithy build plugin.
+This project will eventually be removed entirely as the CLI is deprecated.
+For more details, please see `TestModels/aws-sdks/sqs/README.md`.
+
+## Build
+
+### .NET
+
+1. Generate the Wrappers using `polymorph`
+```
+make polymorph_dafny polymorph_net
+```
+
+2. Transpile the tests (and implementation) to the target runtime.
+```
+make transpile_net
+```
+
+3. Generate the executable in the .NET and execute the tests
+```
+make test_net
+```
