+CKB is currently tested mainly with `stable-1.32.0` on Linux and Mac OSX.
 
 We recommend installing Rust through [rustup](https://www.rustup.rs/)
 
 ```bash
 # Get rustup from rustup.rs, then in your `ckb` folder:
-rustup override set 1.31.1
+rustup override set 1.32.0
 rustup component add rustfmt
