Installing the Glossary for WordPress plugin is quite easy. From your dashboard, head over to the Plugins page > Add new, and input “glossary codeat” in the search field. Once located, simply click “Install Now” and then “Activate.”
Alternatively, you can manually install the plugin. Download the .zip file from the WordPress.org repository, unzip the folder and upload it through FTP inside the
/wp-content/plugins/ folder in your WordPress installation.
