TrioCMS installs like any WordPress plugin:
- From your WordPress admin, go to Plugins, Add New and upload the TrioCMS package.
- Activate the suite.
- Enable the individual modules you want from the TrioCMS settings screen.
Because TrioCMS is a plugin suite rather than a theme or a core patch, it works alongside your existing theme and other plugins. See How the plugin suite is organized to understand the modules.
