 ## Overview
-OnlyOffice Document Server
+This package installs a Document Server application supporting collaborative edition of OnlyOffice documents. Edition of documents requires a Client application such as the [OnlyOffice connector for Nextcloud](https://apps.nextcloud.com/apps/onlyoffice) or the [ONLYOFFICE Desktop Editors](https://www.onlyoffice.com/fr/download-desktop.aspx)
 
 **Shipped version:** 5.2.8
 
+## Screenshots
+
+![](Link to a screenshot for this app)
+
+## Demo
+
+* A free 30 days demo of Document Server is available from OnlyOffice connector for Nextcloud:
+  * Install Nextcloud and the ONLYOFFICE app (connector)
+  * Go in the Nextcloud administrator settings, section ONLYOFFICE
+  * Tick the box `Connection to demo ONLYOFFICE Document Server`` in Server Parameters
+* Some testing is also possible using [ONLYOFFICE Desktop Editors](https://www.onlyoffice.com/fr/download-desktop.aspx)
+
+## Prerequisite
+You should not install ``onlyoffice`` on your main YunoHost domain, especially if you want to use it with a ``nextcloud`` installed on the same domain.
+* Add a new domain for OnlyOffice in YunoHost 
+  * If your main YunoHost domain was provided by YunoHost, e.g. ``domain.nohost.me``, then you don't have to buy/register a new domain name
+  * Just click on ``I already have a domain``
+  * Type e.g. ``office.domain.nohost.me`` and click on ``Add``
+* Add a Let's Encrypt certificate for this domain
+
+## Configuration of OnlyOffice Server
+* Suppose:
+  * ``yunohost.domain`` is your main YunoHost domain
+  * you have configured ``office.yunohost.domain`` for OnlyOffice, see Prerequisite above
+  * you have Nextcloud installed on ``yunohost.domain/nextcloud`` or ``nextcloud.yunohost.domain``
+* Install ``onlyoffice`` using CLI or web admin
+  * Choose a domain name for OnlyOffice that is different from your Nextcloud domain, e.g. ``office.yunohost.domain`` (or ``office.domain.nohost.me`` previously created)
+  * Choose a path for OnlyOffice, e.g. ``/`` if you install on ``office.yunohost.domain`` (do not install any further app on this domain)
+  * The domain of your Nextcloud instance, e.g. ``yunohost.domain/nextcloud`` or ``nextcloud.yunohost.domain``
+  * Is it a public application? **If you want to connect it to Nextcloud, OnlyOffice should be public**: then select ``Yes`` or ``tick the box``
+
+## How to edit OnlyOffice documents?
+### Web Edition in Nextcloud
+Prerequisite: **OnlyOffice should be public**, see previous section.
+* In Nextcloud apps store, install ``ONLYOFFICE``, i.e. the [OnlyOffice connector for Nextcloud](https://apps.nextcloud.com/apps/onlyoffice)
+* Go in the Nextcloud ``settings``>``Administration``>``ONLYOFFICE``>``Server settings``>``Address of the Document Server``
+* Give the installation domain of your ``onlyoffice``, e.g. ``https://office.yunohost.domain/`` and click ``Save``
+* Create a new document and enjoy!
+
+### Desktop Edition on PC
+* Download and install a [ONLYOFFICE Desktop Editor](https://www.onlyoffice.com/fr/download-desktop.aspx)
+* Start the Editor and Go to ``Connect to cloud``>``Add cloud``
+  * Select ``ONLYOFFICE`` and give the installation domain of your ``onlyoffice``, e.g. ``office.domain.nohost.me``
+  * or (only if you connected ``onlyoffice`` to Nextcloud, see previous section)
+  * Select ``Nextcloud`` and give your nextcloud installation domain, e.g. ``yunohost.domain/nextcloud``
+* Create a new document and enjoy!
