 ==== Installation ====
-[[http://jankarres.de/2013/12/raspberry-pi-kamera-modul-mit-motion-tracking/|Install instructions]]
+<code>apt-get install motion</code>
 ==== Configuration ====
+=== motion.conf ===
+see my configfile below...
 === 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>).

-=== My configuration ===
+==== Troubleshooting ====
+=== libavformat error ===
+"motion: error while loading shared libraries: libavformat.so.53: cannot open shared object file: no such file or directory"
+You might have to install some dependencies
+<code>apt-get install -y libjpeg62 libjpeg62-dev libavformat53 libavformat-dev libavcodec53 libavcodec-dev libavutil51 libavutil-dev libc6-dev zlib1g-dev libmysqlclient18 libmysqlclient-dev libpq5 libpq-dev</code>
+If some are not found, try to get the right version for your current distribution via
+<code>apt-cache search <package></code>
+=== /dev/video0 not found ===
+"vid_v4lx_start: Failed to open video device /dev/video0: No such file or directory"
+Activate the module, /dev/video0 should be there afterwards
+<code>modprobe bcm2835-v4l2</code>
+and add the module to /etc/modules as a new line (persistent)
+<code>bcm2835-v4l2</code>
+=== libavformat error ===
+<code>
+[1:ml1] [NTC] [ALL] [Jun 13 18:42:16] mlp_actions: End of event 1
+[1:ml1] [NTC] [ALL] [Jun 13 18:42:16] motion_loop: Thread exiting

+[0:motion] [NTC] [ALL] [Jun 13 18:42:17] main: Motion terminating
+</code>
+Motion just stops. If you activated "daemon mode" via config you might need to edit your servicefile.
+Edit /lib/systemd/system/motion.service
+<code>
+ExecStart=/usr/bin/motion
+to
+ExecStart=/usr/bin/motion -n
+</code>
+then
+<code>
+systemctl daemon-reload
+systemctl restart motion.service
+</code>

+==== My configurationfile ====
+This is the dozencrows config with my values, some things have changed in the current "apt-get"-version. Most of the config is the same, just compare it with the new one
 <code sh motion.conf>
 # /etc/motion.conf
