 The file `depends` contains a list of tools needed.  The format of this

+## Getting started with building your images
+
+Getting started is as simple as cloning this repository on your build machine. You
+can do so with:
+
+```bash
+git clone --depth 1 https://github.com/RPI-Distro/pi-gen.git
+```
+
+Using `--depth 1` with `git clone` will create a shallow clone, only containing
+the latest revision of the repository. Do not do this on your development machine.
+
+Also, be careful to clone the repository to a base path **NOT** containing spaces.
+This configuration is not supported by debootstrap and will lead to `pi-gen` not
+running.
+
+After cloning the repository, you can move to the next step and start configuring
+your build.

+# Regarding Qcow2 image building
+
+### Get infos about the image in use
+
+If you issue the two commands shown in the example below in a second command shell while a build
+is running you can find out, which network block device is currently being used and which qcow2 image
+is bound to it.
+
+Example:
+
+```bash
+root@build-machine:~/$ lsblk | grep nbd
+nbd1      43:32   0    10G  0 disk
+├─nbd1p1  43:33   0    10G  0 part
+└─nbd1p1 253:0    0    10G  0 part
+
+root@build-machine:~/$ ps xa | grep qemu-nbd
+ 2392 pts/6    S+     0:00 grep --color=auto qemu-nbd
+31294 ?        Ssl    0:12 qemu-nbd --discard=unmap -c /dev/nbd1 image-stage4.qcow2
+```
+
+Here you can see, that the qcow2 image `image-stage4.qcow2` is currently connected to `/dev/nbd1` with
+the associated partition map `/dev/mapper/nbd1p1`. Don't worry that `lsblk` shows two entries. It is totally fine, because the device map is accessible via `/dev/mapper/nbd1p1` and also via `/dev/dm-0`. This is all part of the device mapper functionality of the kernel. See `dmsetup` for further information.
+
+### Mount a qcow2 image
+
+If you want to examine the content of a a single stage, you can simply mount the qcow2 image found in the `WORK_DIR` directory with the tool `./imagetool.sh`.
+
+See `./imagetool.sh -h` for further details on how to use it.
+
+### Disconnect an image if something went wrong
+
+It can happen, that your build stops in case of an error. Normally `./build.sh` should handle image disconnection appropriately, but in rare cases, especially during a Docker build, this may not work as expected. If that happens, starting a new build will fail and you may have to disconnect the image and/or device yourself.
+
+A typical message indicating that there are some orphaned device mapper entries is this:
+
+```
+Failed to set NBD socket
+Disconnect client, due to: Unexpected end-of-file before all bytes were read
+```
+
+If that happens go through the following steps:
+
+1. First, check if the image is somehow mounted to a directory entry and umount it as you would any other block device, like i.e. a hard disk or USB stick.
+
+2. Second, to disconnect an image from `qemu-nbd`, the QEMU Disk Network Block Device Server, issue the following command (be sure to change the device name to the one actually used):
+
+   ```bash
+   sudo qemu-nbd -d /dev/nbd1
+   ```
+
+   Note: if you use Docker build, normally no active `qemu-nbd` process exists anymore as it will be terminated when the Docker container stops.
+
+3. To disconnect a device partition map from the network block device, execute:
+
+   ```bash
+   sudo kpartx -d /dev/nbd1
+   or
+   sudo ./imagetool.sh --cleanup
+   ```
+
+   Note: The `imagetool.sh` command will cleanup any /dev/nbdX that is not connected to a running `qemu-nbd` daemon. Be careful if you use network block devices for other tasks utilizing NBDs on your build machine as well.
+
+Now you should be able to start a new build without running into troubles again. Most of the time, especially when using Docker build, you will only need no. 3 to get everything up and running again.

+Please note there is currently an issue when compiling with a 64 Bit OS. See
+https://github.com/RPi-Distro/pi-gen/issues/271
+
+A 64 bit image can be generated from the `arm64` branch in this repository. Just
+replace the command from [this section](#getting-started-with-building-your-images)
+by the one below, and follow the rest of the documentation:
+```bash
+git clone --depth 1 --branch arm64 https://github.com/RPI-Distro/pi-gen.git
+```
+
+If you want to generate a 64 bits image from a Raspberry Pi running a 32 bits
+version, you need to add `arm_64bit=1` to your `config.txt` file and reboot your
+machine. This will restart your machine with a 64 bits kernel. This will only
+work from a Raspberry Pi with a 64-bit capable processor (i.e. Raspberry Pi Zero
+2, Raspberry Pi 3 or Raspberry Pi 4).

+  * lxinput - remove redundant changes to openbox config file
+  * plymouth - set KillMode to mixed to suppress warning message
+  * raspi-config - add option to switch composite video
+  * raspi-config - add option to switch to legacy camera mode
+  * raspi-config - add option to set resolution for headless connections
