Kerbel building: 'make config' command

Hello, I started to learn Linux SuSe 7.1 and at moment analyze how Kernel is build. In Kernel HOWTO is written that command 'make config' invokes building Kernel, however I receive message **no rule to make target 'config' . Stop** . Where I can get more detail explanation on configuring system to work 'make config' correctly ? Thanks for help in advance. Kestutis
