+## Basic Usage:
+
+Download the needed images for your device and put them beside this script.
+
+Remember to eventually turn of NetworkManager or place a dumb switch in between so that the link stays up during repowering the FritzBox.
+For the 7520 I had good experience plugging the device in, waiting until all LEDs are lit during boot, and start the script directly after this.
+
+Using network autoconfiguration with privileges (uboot images must be in the same folder too):

+## Windows Usage
+
+1. disable Wifi
+2. allow incoming port 69/UDP or disable Firewall
+3. run script as administrator, so that it can change the current ip address and open Port 69/UDP
+4. enable Firewall
+5. enable Wifi again
+
+For other devices than the 7520/7530/1200, less privileges are needed (no TFTP) if the initial ip address is set manually in the network adapter configs.

 Exceptions apply for the FRITZ!Box 4040. This device needs a special bootloader-image for use with the flash-script. Flashing with a sysupgrade image won't work.
 
+More exceptions are the FRITZ!Box 7520/7530 and FRITZ!Repeater 1200, which use a two step TFTP flashing procedure which includes an additional uboot image.
