Doc for configuration RAID

[abdelkader belahcene <abelahcene@gmail.com>]

HI,
I want to add to my working system, disks using RAID.
I found doc for Fedora ,  the packages used are not the same in debian
 ( it seems to me, for example on fedora  there are commands like  mkraid and raidstart   
  I didn't find them in debaian package : I installed mdadm dmraid   ),

please somebody tells me where to find an easy doc to configure the raid for debian.
thnks a lot.
regards
