• Place this plugin folder into plugins directory of Roundcube
• Add nextcloud to $config['plugins'] in your Roundcube config
• Upload contents of upload_to_nextcloud_apps into your apps directory for Nextcloud and enable plugin within Nextcloud.

NB: When downloading the plugin from GitHub you will need to create a directory called nextcloud and place the files in there, ignoring the root directory in the downloaded archive directory in the downloaded archive.

• To avoid cross-domain errors you should use the same url (domain) for Roundcube and nextcloud (See the reverse proxy documentation, to use nextcloud and Roundcube on separate servers with Apache)
• Add and enable "roundcube_external" apps to your nextcloud instance (in nextcloud/apps/)
• You can also add melanie2 theme to nextcloud

• In Roundcube plugin you need to rename config.inc.php.dist to config.inc.php. And configure your nextcloud URL and a random DES key of 24 characters.
• In nextcloud, you need to edit the config.php file and add a 'roundcube_nextcloud_des_key' property with the same DES key.

• Will not automatically login at this point. It does logout of your nextcloud seesion when you logout of Roundcube. I just started this thing.
