You'll get sticky dough at the beginning, don't worry. Knead it on a working surface for a few minutes, it'll not be sticky as time passes. Remove/clean the sticky dough bits from your hands, or oil your hands, it'll help. If that doesn't help, cover the dough with a cling film and rest it for 10-20 minutes. It'll be more manageable then, and not sticky anymore. Trust the process!
