DPNI scheme: how to set up if i don't have experience

I just moved to UK and would like to set up DPNI scheme to pay both tax income & national insurance. I already received national insurance number. My company is registered in Kazakhstan and doesn't have representative office in Uk. all my income is in local currency - Tenge. I already read thousand of materials, but i still don't understand how to register myself for DPNI scheme and kindly ask for step by step instruction. Thank you in advance
