 =====Config the Boot Partition=====
-Create locally a file named as "wpa_supplicant.conf" with the following content:
+Insert the SD-Card again, after creating of the Image on the SD-Card has finished.\\
+The SD-Card should be visible in the File-Explorer as ''boot''.\\

+To make the Zero able to connect to the WiFi, it must get some settings to get this done.\\
+The easiest way is to create a text file locally named as ''wpa_supplicant.conf'' with the following content:

+Check the services which are not needed for the headless setup:
+<code>
+systemd-analyze blame

+Google "raspberry zero systemd-analyze blame" to find tips, because this is a bit out of scope to include it in the Wiki.\\

+=====Power consumption=====
+====HDMI====
+Running a headless Zero, there's no need to power the display circuitry.\\
+Add the following line in ''/etc/rc.local'' to disable HDMI on boot.
+<code>/usr/bin/tvservice -o</code>
+(-p to re-enable).\\
+Approximately 25mA reduction.\\
+ \\
+=====Special Boot Options=====
+To be able to use pin 27 and 28 as normal I/O, add an extra line in the /boot/config.txt:
+<code>
+force_eeprom_read=0
+</code>
+  * https://www.raspberrypi.org/documentation/configuration/config-txt/boot.md

 =====Notes=====
+====SFTP File Transfer====
+WinSCP and FileZilla can be used for transferring files to and from the Raspberry Pi.\\
+For more information see:
+  * https://www.raspberrypi.org/documentation/remote-access/ssh/sftp.md
+====SSH====
   * The terminal/console commands **ssh** and **scp** are available under Linux, Windows10 and Apple macOS.
   * If "raspberrypi" cannot be resolved, "Could not resolve hostname raspberrypi", check the router and use the IP address instead: \\ {{:rocnet:cam:fritz.png?400}}
+====Wait for Network at Boot====
+Under specific network conditions, the following system option (sudo raspi-conf) must be activated, if the WIOpi or CAM does not start at boot:
+  * **1** System Options
+    * **S6** Network at Boot ((Select wait for network connection on boot))
+ \\
+====Disable screen saver====
+In case of a connected display, none headless, without user interaction.\\
+Edit the lightdm configuration:
+<code>$ sudo nano /etc/lightdm/lightdm.conf</code>
+find this section, and add the extra options:
+<code>
