 ## Status
 
 🚨 WARNING 🚨: This project is under active development. Be aware that large breaking changes may happen before 1.0 is reached.
 
-This project is the successor to the `azure_sdk*` crates from [MindFlavor/AzureSDKForRust](https://github.com/MindFlavor/AzureSDKForRust). The crates have been renamed, so those older crates should be considered fully deprecated. See [history](HISTORY.md) for more details.
