 We will compile the stable 1.2.2 release. If you want to compile the master branch, don't execute `git checkout release-1.2`. I haven't tested it, so it might not work!
 
     git clone https://github.com/clementine-player/Clementine.git && cd Clementine
     git checkout release-1.2
     cd bin
 
-### Preparing the build enviroment
+## Preparing the build enviroment
 Since the Raspberry Pi has only a limited amount of ram, we need to create a swap file. Without it, compiling fails when building the translations.
 
     sudo dd if=/dev/zero of=swapfile bs=1M count=512
     sudo mkswap swapfile
     sudo swapon swapfile
 
-### Compile
+## Compile
     cmake ..
     make -j2
 
 Wait. A (very long) time.
 
-### After compiling
+## After compiling
 A swap file on a flash memory is not healty, so we remove the created swap file after compiling.
 
     sudo swapoff swapfile
     sudo rm swapfile
 
-### Install Clementine runtime dependencies
+## Install Clementine runtime dependencies
 Raspbian doesn't have gstreamer plugins installed by default, so we have to do this now.
 
     sudo apt-get install gstreamer0.10-alsa gstreamer0.10-tools gstreamer0.10-ffmpeg \
         gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-fluendo-mp3 
 
-### Setting up Clementine
+## Setting up Clementine
 Start Clementine with `./clementine`. The first start takes quite long as Clementine has to setup the database. After you see the main window, you should disable moodbar generation and glowing. They take too many resources you need for playback.
 For me setting the output plugin to `Audio sink (ALSA)` and output device to `hw:0,0` gave pretty good audio results. I don't recommend using pulseaudio.

 Note: Clementine is quite slow on the Raspberry Pi, so be patient when using it. Clementine Remote works very well on the Raspberry Pi.
