It appears I didn’t add my company name in the initial set up. How can I do this now please?

3. Enter the new name in the Company name field.
4. If the company's legal name is different from the Company name you entered:
   1. Enter the legal name in the Legal name field.
   2. Otherwise, select the Same as company name checkbox.
5. Enter or edit your Companies House Registration Number (CRN) in the field provided.
