Update one of your channels. Set the description — the line a stranger reads in a search result or a link unfurl, at most 160 characters, empty to clear it and go back to naming the newest presentations. Set the avatar from an image URL, which is fetched, center-cropped square and resized. Pass either or both. Omit handle to use your default channel.
