The plugin can be installed either through the Plugin Store or through Composer.
Open the control panel for your website. Navigate to Settings → Plugins and search for Neo. Click Install.
Run the following command in the root directory of your Craft project:
composer require spicyweb/craft-neo
Neo requires Craft CMS 4.0.0 or later.
Neo has the same PHP version requirement as Craft CMS 4.0.0: PHP 8.0.2 or later.
Neo supports the same browsers and versions that Craft CMS 4.0.0 supports. While Neo may work on browsers outside of those listed, this list is what Neo explicitly supports. The best option is to use an up-to-date major browser.
