 For your application, you can specify any serializable type as the `Message`
 type in your `Contract` implementation. To send a message, use the
-[`ContractRuntime`](https://docs.rs/linera-sdk/latest/linera_sdk/struct.ContractRuntime.html)
-made available as an argument to the contract's [`Contract::load`] constructor.
-The runtime is usually stored inside the contract object, as we did when
-[writing the contract binary](./contract.md). We can then call
-[`ContractRuntime::prepare_message`](https://docs.rs/linera-sdk/latest/linera_sdk/struct.ContractRuntime.html#prepare_message)
-to start preparing a message, and then
-[`send_to`](https://docs.rs/linera-sdk/latest/linera_sdk/struct.MessageBuilder.html#send_to)
-to send it to a destination chain.
