Creating user profiles with edit, delete and save

Hi please can you tell me how I can implement and code a user profile after logging in using firebase. I want the user to be able to add, edit or delete personal information and for it to be saved so they can go back further down the line and view the information saved. I have been searching online for tutorials on this and haven’t found anything. Please would you be able to assist me with this thank you
