Nostr: How do I set up my Nostr profile?

Use a client to publish profile metadata such as a display name, description, and picture under your key.

Short answer

Use a client to publish profile metadata such as a display name, description, and picture under your key. You may also add a NIP-05 identifier if you control a domain or use a provider. Your profile is a signed event that clients retrieve from relays, so changes can take time to appear everywhere. Avoid publishing personal details you want to keep private.
