+
+## Basic usage
+The systemd service instance name is mapped to the video device number. So for example:
+
+```sh
+systemctl start fake-background-webcam@0.service
+```
+
+would use `/dev/video0` as the source and create `/dev/video20` as the virutal camera with fake background.
+
+## Customization
+Override the systemd unit file: 
+
+```sh
+systemctl edit fake-background-webcam@0.service 
+#edit
+systemctl daemon-reload
+systemctl restart fake-background-webcam@0.service
+```
+
+
+```sh
+[Service]
+# Change folder with background/mask images and add additional arguments 
+# See https://github.com/fangfufu/Linux-Fake-Background-Webcam#fakecamfakepy
+Environment=IMAGE_FOLDER=/home/myBackground FAKE_BACKGROUND_WEBCAM_ARGS="--hologram --scale-factor 1"
+
+# To avoid automatic loading/removing of the v4l2loopback kernel module
+ExecStartPre=
+ExecStartPost=
+
+ 
+```
+
+It is possible to have multiple cameras sharing the same bodypix detector. Only disable the `Pre/Post` commands (for all `@` instances) as shown above and load the modules manually. For example:
+
+```sh
+modprobe v4l2loopback video_nr=20,21 card_label="Fake Background cam1","Fake Background cam2" exclusive_caps=1
+
+```
