+## Abstract
+
+This docker-compose allows to easily run a Nextcloud instance with Collabora.
+
+## Prerequisites for production use
+
+- Domain records:
+  - One record for Nextcloud (eg: `nextcloud.example.com`)
+  - One record for Collabora (eg: `collabora.example.com`)
+  - BOTH records must be (resolvable AND accessible) from (Nextcloud container AND Collabora container AND final users)
+- HTTPS for Nextcloud and Collabora (eg: [Let’s Encrypt](https://letsencrypt.org/))
+- Reverse proxy for SSL termination
+
+## Installation
+
+### Tweak files
+
+- `env`
+  - Set `TZ`
+    - The timezone to be used in the container (See [List_of_tz_database_time_zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones))
+    - Example: `Europe/Paris`
+  - Generate secure password for `POSTGRES_PASSWORD`
+    - Password to be set (and used) for the Nextcloud database user. It will only be set when postgres files (`./data/postgres/data/...`) are created. Any further change won't update it.
+    - Example: [passwordsgenerator.net](https://passwordsgenerator.net/)
+  - Generate secure password for `NEXTCLOUD_ADMIN_PASSWORD`
+    - Password to be set for Nextcloud `root` user. It will only be set when Nextcloud will install itself. Any further change won't update it.
+    - Example: [passwordsgenerator.net](https://passwordsgenerator.net/)
+
+- `env_collabora`
+  - Set `domain`
+    - Regexp for domain(s) allowed to used Collabora. It must match your Nextcloud domain.
+    - Example: `nextcloud\.example\.com` (Note the backslashes to escape the dots)
+  - Generate secure password for `password`
+    - Password to be set for Collabora admin panel (https://collabora.example.com/loleaflet/dist/admin/admin.html)
+    - Example: [passwordsgenerator.net](https://passwordsgenerator.net/)
+
+- `docker-compose.yml`
+  - Set restart policies
+    - Uncomment `restart` lines to allow docker to automatically start the containers on reboot.
+
