Debian Sid first time user

[Rodolfo Medina <rodolfo.medina@gmail.com>]

Hi to all the Debian users community.

I've been using Debian for a couple of years now (coming from Mandrakelinux)
and have been happy with stable versions, Sarge and then Etch.  Now for
particular needs I want to try to use Sid with a > = 2.6.25-2-686 kernel.

Please can anybody indicate how to fetch and install a Debian Sid distribution
and how to manage it after installation (packages and so on)?  I didn't find
any help on www.debian.org.  Besides, large downloads are not easy for my
connection.

Thanks in advance for any reply
Rodolfo
