How to add new device driver?

hi ,
I am nataraj asture final year student of B.E .Me and our friends are doing project to develope a RAM disk driver in linux Operating system we have problem in adding that driver to our kernel by removing the old kernel.
I have also read one articles in many sites but they r not clearly mentioned the steps and problems occuring during configuration.
If someone helps me it will be better for us to successfully load our driver onto the system.
:fart: :firedevil

Try by loading the module?

insmod to add module
rmmod to remove module
lsmod to list loaded modules

I've been using linux quite some time (but still consider myself a n00b).
Anytime I've had to load a driver, I used insmod.

I don't have any other experience other than that.

The distros I use seem to find all my hardware. :)
