+# Crates that extend Rusoto
+
+Rusoto's current focus is to support all AWS services. This means higher level functionality present in other AWS SDKs are not currently available in Rusoto. See [https://github.com/rusoto/rusoto/issues/1098](https://github.com/rusoto/rusoto/issues/1098) for more information on where Rusoto efforts are currently focused.
+
+While Rusoto doesn't support various higher level functionality or better ergonomics, there are third party crates available that use Rusoto and provide this behavior.
+
+A non-exhaustive list of projects that build on Rusoto to make it more ergonomic or provide higher level functionality:
+
+1. [dynomite](https://github.com/softprops/dynomite): `make your rust types fit dynamodb and visa versa`
+2. [envy-store](https://github.com/softprops/envy-store): `deserialize AWS Parameter Store values into typesafe structs`
+3. [S4](https://gitlab.com/pgerber/s4): `Simpler Simple Storage Service for Rust`
+
+If you'd like to add an example to this list, please open an issue or pull request on the [rusoto.org repo](https://github.com/rusoto/rusoto.github.io).
