 This is a sample TypeScript project [with full source & config on GitHub](https://github.com/polkadot-js/docs/tree/master/docs/api/examples/promise/typegen), that uses `@polkadot/typegen` to generate type definitions that can be used to decorate the `@polkadot/api`. It uses both types defined for the specific chain as well as the chain metadata to generate TypeScript interfaces. This means that interfaces such as `api.query.*`, `api.tx.*` and `api.consts.*` will be decorated based on chain-specific information, instead of an un-augmented catch-all definition.
 
-**NOTE** This is built using the updates in the `1.4.0` api track and as such it uses the latest (at the time of writing) `@polkadot/api 1.4.0`. If you want to play on your own, it is also suggested that you use the `1.4+` series since some generation types have moved around internally, making it easier to augment.
+**NOTE** This is built using the updates in the `10.9.1` api track and as such it uses the latest (at the time of writing) `@polkadot/api 10.9.1`.
