ONLYOFFICE Server is a free collaborative online office suite comprising viewers and editors for texts, spreadsheets and presentations, fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and enabling collaborative editing in real time.
1. Install [OnlyOffice Server](https://github.com/YunoHost-Apps/onlyoffice_ynh) in a different domain than the one used by Nextcloud: `https://onlyoffice.domain.org` and `https://domain.org/nextcloud` (for example)
- Connect to Nextcloud as admin and install ONLYOFFICE Connector: -> Applications -> install ONLYOFFICE. (ONLYOFFICE Connector doesn't need to match your OnlyOffice Server version number).
- In Settings (`https://domain.org/nextcloud/settings/admin/onlyoffice`), enter your OnlyOffice Server address (for example: `https://onlyoffice.domain.org`)
