What's in this directory?

These are files containing source code for the Debian operating system.

How do I use these files?

The files here are in "jigdo" format. Use jigdo tools to download the contents of the complete ISO image files from what's here and a normal Debian mirror. You should end up with an exact copy of each ISO image as though you'd downloaded it directly via HTTP or FTP.

Once you have downloaded all the ISO images you want, you will typically need to write them to installation media.

What size and type of media will I need?

The images described here are sized to be written to writeable DVD media at a minimum, but may be written to larger media if needed.

How can I verify my download is correct and exactly what has been created by Debian?

There are files here (SHA512SUMS, etc.) which contain checksums of the images. These checksum files are also signed - see the matching .sign files. Once you've downloaded an image, you can check:

• that its checksum matches that expected from the checksum file; and
• that the checksum file has not been tampered with.

For more information about how to do these steps, read the verification guide.

Non-free Firmware

This Debian image build only includes Free Software where possible. However, many systems include hardware which depends on non-free firmware to function properly so this build also includes those firmware files for those cases. See the Debian Wiki non-free firmware page for more information.

Other questions?

See the Debian CD FAQ for lots more information about Debian CDs and installation.

The images here were put together by the Debian CD team , using debian-cd and other software.
