 ### Nightly Compiler
 
-Bevy requires nightly rust right now. It currently uses [specialization](https://github.com/rust-lang/rfcs/blob/master/text/1210-impl-specialization.md) features, which are unstable. If specialization goes stable soon then we can go back to a stable compiler. In the meantime, we will try our best to remove specialization usage so we can go back to stable.
