If you're a Mac or Windows user, the best way to install Compose and keep it up-to-date is Docker for Mac and Windows.

Docker for Mac and Windows will automatically install the latest version of Docker Engine for you.

Alternatively, you can use the usual commands to install or upgrade Compose:

curl -L https://github.com/docker/compose/releases/download/1.13.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

See the install docs for more install options and instructions.
