10 | ## Command-line parameters | |
11 | The script accepts certain command-line parameters to enable or disable specific OS features, services and configuration settings. These parameters are passed to the `rpi2-gen-image.sh` script via (simple) shell-variables. Unlike enviroment shell-variables (simple) shell-variables are defined at the beginning of the command-line call of the `rpi2-gen-image.sh` script. |

|
90 | ## Flashing the image file | |
87 | After the image file was succesfully created by the `rpi2-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi2 computer. This can be performed by using the tools `bmaptool` or `dd`. Using `bmaptool` will probably speed-up the copy process because `bmaptool` copies more wisely than `dd`. |
