Install the plugin
This guide describes a plugin for Archi that lets a team of analysts collaborate on models.
Compared to coArchi, this plugin offers a simpler user interface. A single click synchronizes model changes with the server, and a streamlined dialog handles conflict resolution.
You can also use Architeezy as a portal for publishing models. Models become immediately available to all stakeholders, with no need to install desktop Archi.
Download the plugin.
Launch Archi. From the main menu, select Help → Manage Plug-ins... In the dialog that appears, click Install... and select the downloaded file:

Restart Archi.
