https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel out of date

[mahesh]

There is text
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-disco.git

This code is not working. This is my log:

Cloning into 'ubuntu-disco'...
fatal: remote error: no such repository: /ubuntu/ubuntu-disco.git

Please fix this example. And check page on the whole. I afraid it contains a lot of deprecated information... I try to build my own kernel, but I got a lot of problems...
