 === Maskfile ===
+The maskfile is used to ignore certain areas with moving objects (like trees, pedestrians, cars) which normally would cause motion to capture pictures/videos. The file must have the same width and height as the picture captured by your camera.
+Take a captured picture, paint all the correct areas white, the ones you want to ignore black. //You can also use different gray tones for different sensitivity (never tried).//
+Copy the picture to your Raspberry and convert it to the correct format.
+<code>
+djpeg -grayscale -pnm <YOURPICTURE> > maskfile.pgm
+</code>
+If djpeg is missing, install the following package (libjpeg-progs - Programs for manipulating JPEG files)
+<code>
+apt-get install libjpeg-progs
+</code>
+Place your maskfile next to your "motion.conf" (in /etc/motion) and set the maskfile in your config (syntax: mask_file <FILE>).
