It is possible to perform mass deployment of the Nextcloud desktop client by passing certain command-line parameters from the deployment step to Nextcloud desktop client executable after the initial setup.
This will allow desktop client to generate a config (.cfg) file that will be used during subsequent launches.
A config file will have a corresponding account written into it similar to if you have added it manually via the desktop client's UI.
The desktop client will exit with code 0 if account has been added successfully, or 1 in case of failure.
Detailed failure message is printed to the desktop client logs.

The following parameters are supported:

``--userid``
        (required) userId (username as on the server) to pass when creating an account via command-line.

``--apppassword``
        (required) appPassword to pass when creating an account via command-line (see the ``login-flow`` section in server documentation on how to generate the app password).

``--localdirpath``
        (optional) path where to create a local sync folder when creating an account via command-line. If skipped, then default local sync folder path (/home/<userid>/Nextcloud<n> for Linux/mac or C:/<userid>/Nextcloud<n> for Windows) will be generated by desktop client.
        
``--isvfsenabled``
        (optional) whether to set a VFS or non-VFS folder (1 for 'yes' or 0 for 'no') when creating an account via command-line. Default is 0.

``--remotedirpath``
        (optional) path to a remote subfolder when creating an account via command-line. e.g. If the server has folders "/Photos", "/Documents", "/Music" you can pass "/Music" and then this folder will get set up as remote root.

``--serverurl``
        (required) a server URL to use when creating an account via command-line. (NOTE: There is another parameter supported by Nextcloud desktop client ``--overrideserverurl`` but it SHOULD NOT be used here as it is intended for setup via UI with wizard)

Examples:

- ``C:\Program Files\Nextcloud\nextcloud.exe" --userid admin --apppassword Jliy12356785jxnHa2ZCiZ9MX48ncECwDso95Pq3a5HABjY34ZvhZiXrPfpKWUg7aOHAX5 --localdirpath "D:\\Nextcloud-sync-folder" --remotedirpath /Music --serverurl "https://cloud.example.com" --isvfsenabled 1"`` - this will create a config file for user admin on the server https://cloud.example.com and set a remote root folder to "Music", the local sync folder will get created with VFS mode.
- For Linux and mac the same example as above will work but ``nextcloud.exe path`` and ``--localdirpath`` value should get changed to platform specific format (e.g. ``no .exe extension`` and ``/home/<user folder>`` format)
