+## Installation
 
-<MissingDocs />
\ No newline at end of file
+Nextcloud requires nginx to be installed. Please install the dependency first, and then install Nextcloud.
+
+```bash
+sudo box install nginx
+sudo box install nextcloud
+```
+
+## Accessing Nextcloud
+
+You can access nextcloud at `https://<hostname.tld>/nextcloud`.
+
+The installation will automatically create the Nextcloud administrator user using your master username and password.
+
+## User management
+
+Nextcloud manages its users in its own database. `box` will create, delete and change passwords in it for you when you make those changes. This only works in the box -> nextcloud direction, which means changing a password in nextcloud will not have an impact on the rest of the system.
+
+You can however make Nextcloud users for non-`box`-based users as well through the administration portal. 
+
+## Service control
+
+Nextcloud is an application written by PHP, and therefore it does not have its own service, as it is powered by the PHP-FPM stack.
+
+## Troubleshooting
+
+import Troubleshooting from '../snippets/troubleshooting.md';
+
+<Troubleshooting />
+
+### Domain is not in "trusted domains"
+Nextcloud requires to know which domains/IPs/host names it should expect traffic from for security reasons. It will give you an error when it is being accessed from a source it does not recognize.
+
+Box attempts to guess these based on your IP, your machine's hostname and the value it has for the FQDN, as well as the `server_name` value in your nginx configuration, and adds all of those to the "trusted domains" key.
+
+You can manually change these by following the commands below. Please note: the values are stored in an array, and the value must be set to the index you desire it to be on. Therefore if you have 6 entries, you should add your domain to the 7th position.
+
+```bash
+cd /srv/nextcloud
+# Show all the values currently configured
+sudo -u www-data php occ config:system:get trusted_domains
+# Get the current amount of entries
+sudo -u www-data php occ config:system:get trusted_domains | wc -l
+# Set your value to the next index, e.g. <index> = 7
+sudo -u www-data php occ config:system:set trusted_domains <index> --value="<domain.tld>"
+```
+
+You should be able to connect to your instance now.
