+### Command Line
+As of v0.4.0, the add-in can be installed via command line with custom setting passed as parameters. This works by calling `msiexec` on the .msi installer file. The following parameters can be passed to the installer to preconfigure the Jitsi Meet Outlook add-in settings (all are optional):
+* `TARGETDIR`: Path to the install directory.
+* `DOMAIN`: Custom domain.
+* `ROOMID`: A default room ID new Jitsi Meet appointments get assigned.
+* `REQNAME`: Require name by default in new Jitsi Meet appointments. (True/False)
+* `NOAUDIO`: Mute audio by default in new Jitsi Meet appointments. (True/False)
+* `NOVIDEO`: Disable video by default in new Jitsi Meet appointments. (True/False)
+
+Example install command: `msiexec /i "C:\Downloads\JitsiMeetOutlook-v0.4.0-windows-x64.msi" TARGETDIR="C:\Program Files (x86)\Jitsi Meet Outlook" DOMAIN="my.domain.com" ROOMID="PermanentRoomName" REQNAME="True" NOAUDIO="True" NOVIDEO="True" /passive`
+
+All settings can be changed from the settings menu after installation.
