 - **fabric_contract_api** - Contains the Python contract API used to write smart contracts with the high-level contract programming model.
 - **fabric_shim** - Contains the Python classes that implement the chaincode shim API and the way to communicate with Fabric peers.
+- **examples** - Example chaincode implementations. See the
+  [examples README](examples/README.md) and the
+  [examples structure](examples/STRUCTURE.md) for the layout, conventions,
+  and quick start.
