#### Important December update: Homebrew-Cask will now be kept up to date together with Homebrew (see [#15381](https://github.com/caskroom/homebrew-cask/pull/15381) for details). If you haven’t yet, run `brew uninstall --force brew-cask; brew update` to switch to the new system.
#### Important: At some point in the future Homebrew-cask will change its behaviour from linking apps to moving them. See [issue #13201](https://github.com/caskroom/homebrew-cask/issues/13201) for details.
Homebrew-Cask extends [Homebrew](http://brew.sh) and brings its elegance, simplicity, and speed to the installation and management of GUI Mac applications such as Google Chrome and Adium.
It’s implemented as a `homebrew` [external command](https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/External-Commands.md) called `cask`.

Finally, if it's been a while since you last updated Homebrew-Cask, you may still have the old `phinze/cask` tap installed. Run the following to clean up, then try your command again:
If the issue persists, please use our [bug report template][bug_report_template] to report the output of running the problematic command with the `--verbose` flag, along with the output of `brew cask doctor`.
