UK company strike off

I would like a step by step guide of striking off a company and filing the final accounts, corporation tax and any other works that are required. So I am not looking for you to do the work but guide me. Company is active, small limited company, been trading for less than 2 years and has been dormant for the past few months. Accounts and CT are due which I shall also get done. so the job is pretty much tackling on the tasks to close, ie DS01 etc. Can you help
