+====== APFEL/HV raspberry pi======
+Stand: 18/8/2021
+=== Configuration ===
+  * Start with a raspbian image
+  * Set up a user with username: ''pi'', and password: standard ''agmaas'' password
+  * To enable the I2C bus and set the correct frequency, uncomment the following line from ''/boot/config.txt''
+  dtparam=i2c_arm=on
+and modify it to
+  dtparam=i2c_arm=on,i2c_arm_baudrate=400000
+=== Software installation ===
+  * Create a directory ''/home/pi/apfel_dev''
+  * In that directory clone the following repositories
+    * ''https://gitlab.rlp.net/emp/apfel_interface''
+    * ''https://gitlab.rlp.net/emp/hv_control''
+  * Compile with ''make'' both repositories
+  * Add the following lines to ''/etc/rc.local''
+  /home/pi/apfel_dev/hv_control/start_hv.sh
+  /home/pi/apfel_dev/apfel_interface/scripts/start_apfel.sh
+  * Add the following lines to ''/home/pi/.bashrc''
+  HVDIR=$HOME/apfel_dev/hv_control
+  APFELDIR=$HOME/apfel_dev/apfel_interface
+  alias watch_hv='$HVDIR/watch_hv.sh'
+  alias start_hv='$HVDIR/start_hv.sh'
+  alias watch_apfel='$APFELDIR/scripts/watch_apfel.sh'
+  alias start_apfel='$APFELDIR/scripts/start_apfel.sh'
+  * Reboot the pi to see if everything worked. On startup, the APFEL and HV control programs should be started
+=== Service scripts ===
+  * Through the aliases **''watch_hv''** and **''watch_apfel''**, it is possible to see the output of the respective servers. The log files to which the servers write to are:
+  /home/pi/apfel_dev/hv_control/hvlog.{out,err}
+  /home/pi/apfel_dev/apfel_interface/apfellog.{out,err}
+  * The servers can be killed and restarted through the aliases **''start_hv''** and **''start_apfel''**.
+  * Without arguments, the scripts check if there are running server processes and if so exit with an output like:
+  n. of server processess: 2
+  n. of watch processess: 2
+  processes running, kill first
+  * To kill the processes, call the aliases with the argument ''-kill'' (e.g. ''start_hv -kill'').
+  * **Only for ''start_apfel''**, it is possible to start the server with the verbose flag set by invoking the alias with ''start_apfel -v''.
