how to make a custom kernel which boots a custom initrd.img file

Question

I was mining information on "how to create a kernel" and have created a simple kernel which just prints "my first kernel". Later, I went on to creating a small initrd.img file which launches a "busybox ash -login" command. Now, my question is, how to make the kernel use the initrd.img file to boot into a shell [the $ screen] ??

I am trying to create my own Linux Distribution and so I am trying to understand the basics

I do know my task does not require an initrd but I am curious that's all :)
