 Before you use the `subxt` library, you can use the standalone `subxt` command-line interface to download the metadata for the Substrate node you want to use as the target for submitting transactions.
 The `subxt-cli` tool enables you to perform two key tasks that are critical to using the `subxt` library:
 
-* You can use the `subxt-cli` tool to download the metadata from any target Substrate node.
-* You can use the `subxt-cli` tool to generate the runtime API code from the metadata from any target Substrate node.

 You can use the `subxt` library and `subxt-cli` tool for any node that uses metadata v14 and later.
 For examples of how to use the `subxt` library, see the [examples](https://github.com/paritytech/subxt/tree/master/examples/examples) folder.
