# smex contribution layer for Spacemacs

![Smex](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/contrib/smex/smex.png)

This layer replaces `helm-M-x` by [smex][] which is built on top of `ido`.
`ido` can perform flex matching with the [flx-ido][] mode which is already
activated in the Spacemacs layer.
