+### Building
+
+```
+sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libopencv-dev libeigen3-dev
+[optional] install libk4a1.4-dev and/or librealsense2-dev
+make && sudo make install
+```
+
 ### Usage
 
 **Example 1** - debug/config view of plain webcam: `./surfacecast v4l2 /dev/video0`
 
 **Example 2** - stream Realsense to ![virtual camera device](https://github.com/umlaeute/v4l2loopback): `./surfacecast realsense 0 "videoconvert ! video/x-raw,format=RGB,width=1280,height=720 ! v4l2sink device=/dev/video20"` (mind the quotes around the GStreamer pipeline)
 
-For setting up the virtual camera, install `v4l2loopback-dkms`, copy `config/modules.conf` to `/etc/modules-load.d/` and `config/v4l2loopback.conf` to `/etc/modprobe.d/`, and run `sudo modprobe v4l2loopback`.
+For setting up the virtual camera, install `v4l2loopback-dkms`, copy `config/v4l2loopback-autoload.conf` to `/etc/modules-load.d/` and `config/v4l2loopback-options.conf` to `/etc/modprobe.d/`, and run `sudo modprobe v4l2loopback` (also part of `make install`).
 
 **Example 3** - simple network stream of Kinect Azure: `./surfacecast k4a 0 "jpegenc ! rtpjpegpay ! udpsink host=..."`
