I have been an Epic Clin Doc builder for several years.
Your institution should have how to guides and step by step tip sheets. Try to track down your nurse educator or ask a coworker who is still going to class if they can get you a copy. Most Epic GoLives also include self training modules online. However for admitting, discharge, and meds those process vary from one to the next so it would be best to try and reach out to ask for reinforcement. Don't be shy, there should a team of trainers who are wanting to help.
