 Bevy is a refreshingly simple data-driven game engine built in Rust. It is free and open-source forever!
 
-> [!WARNING]
+> [!WARNING](https://arc.net/l/quote/bvslnemh)
 > Bevy is still in the early stages of development. Important features are missing. Documentation is sparse. A new version of Bevy containing breaking changes to the API is released [approximately once every 3 > months](https://bevyengine.org/news/bevy-0-6/#the-train-release-schedule). We provide [migration guides](https://bevyengine.org/learn/migration-guides/), but we can't guarantee migrations will always be easy. Use only if you are willing to work in this environment. 
 >
 > **MSRV:** Bevy relies heavily on improvements in the Rust language and compiler. As a result, the Minimum Supported Rust Version (MSRV) is generally close to "the latest stable release" of Rust.
