When there is an update for Reach, you will see a notification in your WordPress Dashboard.

Currently automatic updates are not available, so you need to manually download the update by visiting the Reach download page.

Once you have downloaded the .zip file containing the update, use this handy plugin to update Reach without removing the old version first: https://wordpress.org/plugins/easy-theme-and-plugin-upgrades/
