Worked on enhancing the WireGuard VPN client setup documentation within the gl-inet/docs4.x repository, focusing on improving clarity and accuracy for multiple VPN providers. The work involved updating Markdown-based documentation to correct anchor links, revise server update instructions, and remove outdated guidance related to IPVanish public key refresh procedures. By refining these documents, the developer streamlined onboarding for new users and reduced potential confusion, supporting more efficient troubleshooting and support. The technical approach centered on precise documentation practices and version control using git, ensuring that the latest provider workflows were accurately reflected and that the documentation remained consistent and up to date.
