Worked on stabilizing the Next.js Quickstart guide in the auth0/docs repository by updating documentation to support Auth0 SDK v3. Focused on reducing onboarding friction for new users, the work involved pinning the @auth0/nextjs-auth0 dependency to version 3, ensuring that the Quickstart consistently uses a stable and tested SDK. Adjustments were made to the installation command and route handler file path to align with the updated API and directory structure introduced in v3. The contributions centered on Markdown documentation, emphasizing clarity and accuracy to streamline integration for developers adopting Next.js with Auth0 authentication in their projects.
