Ivy is an acronym for Incremental Vertical completYon. While it operates similarly to other completion schemes, such as Icomplete mode, Ivy aims to be more efficient, smaller, simpler, and smoother to use--yet highly customisable.

To try Ivy, call M-x ivy-mode. A default installation of Ivy only includes the generic completion framework, plus completion for file and buffer names.

This package will not install all of Ivy/Swiper/Counsel. For a full-featured experience please install "elpa-counsel", which will also install "elpa-swiper". Hydra users will probably also want "elpa-ivy-hydra".

Counsel is an alternative to Ido, Anything, and Helm.
