Dear Shaik Firoz Basha,
Well, first log in to IRC, it will take you to your profile page there you can see the option Edit Profile click on that and update all the details called for therein. This is called profile details with Address updated.
You can submit self written resources by clicking on the resource tab available in the top row and on various topics you can submit the same. You have to wait for their approval and once you get 10 articles approved, they are called valid articles approved and you can proceed further.
My best wishes.
Thanks & Regards -
