             # rpi23-gen-image
             ## Introduction
-            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `jessie` and `stretch`. Raspberry Pi 3 images are currently generated for 32-bit mode only.
+            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `jessie` and `stretch`. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 64-bit images can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.11.y```).
             ## Build dependencies
             The following list of Debian packages must be installed on the build system because they are essentially required for the bootstrapping process. The script will check if all required packages are installed and missing packages will be installed automatically if confirmed by the user.
             Set Proxy server address. Using a local Proxy-Cache like `apt-cacher-ng` will speed-up the bootstrapping process because all required Debian packages will only be downloaded from the Debian mirror site once.
             ##### `APT_INCLUDES`=""
-            A comma separated list of additional packages to be installed during bootstrapping.
+            A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
+            ##### `APT_INCLUDES_LATE`=""
+            A comma separated list of additional packages to be installed by apt after bootstrapping and after APT sources are set up.  This is useful for packages with pre-depends, which debootstrap do not handle well.
             ---
             ##### `RELEASE`="jessie"
             Set the desired Debian release name. The script at this time supports the bootstrapping of the Debian releases "jessie" and "stretch". `BUILD_KERNEL`=true will automatically be set if the Debian release `stretch` is used.
+            ##### `RELEASE_ARCH`="armhf"
+            Set the desired Debian release architecture.
             ##### `HOSTNAME`="rpi$RPI_MODEL-$RELEASE"
             Set system host name. It's recommended that the host name is unique in the corresponding subnet.
             ---
-            #### Keyboard settings:
+            #### Keyboard settings:
             These options are used to configure keyboard layout in `/etc/default/keyboard` for console and Xorg. These settings can also be changed inside the running OS using the `dpkg-reconfigure keyboard-configuration` command.
             ##### `XKB_MODEL`=""
             ##### `BUILD_KERNEL`=false
             Build and install the latest RPi2/3 Linux kernel. Currently only the default RPi2/3 kernel configuration is used. `BUILD_KERNEL`=true will automatically be set if the Raspberry Pi model `3` is used.
+            ##### `CROSS_COMPILE`="arm-linux-gnueabihf-"
+            This sets the cross compile enviornment for the compiler.
+            ##### `KERNEL_ARCH`="arm"
+            This sets the kernel architecture for the compiler.
+            ##### `KERNEL_IMAGE`="kernel7.img"
+            Name of the image file in the boot partition. If not set, `KERNEL_IMAGE` will be set to "kernel8.img" automatically if building for arm64.
+            ##### `KERNEL_BRANCH`=""
+            Name of the requested branch from the GIT location for the RPi Kernel. Default is using the current default branch from the GIT site.
+            ##### `QEMU_BINARY`="/usr/bin/qemu-arm-static"
+            Sets the QEMU enviornment for the Debian archive. If not set, `QEMU_BINARY` will be set to "/usr/bin/qemu-aarch64-static" automatically if building for arm64.
+            ##### `KERNEL_DEFCONFIG`="bcm2709_defconfig"
+            Sets the default config for kernel compiling. If not set, `KERNEL_DEFCONFIG` will be set to "bcmrpi3\_defconfig" automatically if building for arm64.
             ##### `KERNEL_REDUCE`=false
             Reduce the size of the generated kernel by removing unwanted device, network and filesystem drivers (experimental).
             ##### `BASEDIR`=$(pwd)/images/${RELEASE}
             Set a path to a working directory used by the script to generate an image.
-            ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-rpi${RPI_MODEL}-${RELEASE}
+            ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
-            Set a filename for the output file(s). Note: the script will create $IMAGE_NAME.img if `ENABLE_SPLITFS`=false or $IMAGE_NAME-frmw.img and $IMAGE_NAME-root.img if `ENABLE_SPLITFS`=true.
+            Set a filename for the output file(s). Note: the script will create $IMAGE_NAME.img if `ENABLE_SPLITFS`=false or $IMAGE_NAME-frmw.img and $IMAGE_NAME-root.img if `ENABLE_SPLITFS`=true. Note 2: If the KERNEL_BRANCH is not set, the word "CURRENT" is used.
             ## Understanding the script
             The functions of this script that are required for the different stages of the bootstrapping are split up into single files located inside the `bootstrap.d` directory. During the bootstrapping every script in this directory gets executed in lexicographical order:
             bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
             bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
             ```
+            ## Weekly image builds
+            The image files are provided by JRWR'S I/O PORT and are built once a Sunday at midnight UTC!
