+A hardhat repo that is a collection of Solidity contract **examples** that integrate with or demonstrate the use of Toucan's contracts and infrastructure. Some of these may be used in production and we'll provide links to their prod repos below.
 
 ## OffsetHelper
 
-The `OffsetHelper` contract implements helper functions that simplify the carbon offsetting (retirement) process.
-
-See [./docs/OffsetHelper.md](./docs/OffsetHelper.md) for detailed documentation.
+The `OffsetHelper` contract implements helper functions that simplify the carbon offsetting (retirement) process. It's production version (with actualized related documentation) which is actively maintained can be found [here](https://github.com/ToucanProtocol/OffsetHelper). You can still use the version found in this repo as an example for inspiration purposes.
