Worked on enhancing documentation for tunnel configurations in the coollabsio/coolify-docs repository, focusing on improving user guidance and reducing misconfigurations related to single resource tunnels. The main contribution involved adding a detailed warning about the correct hostname order, addressing a common source of user error and support requests. This update was implemented using Markdown and emphasized clear, actionable instructions for end users. The work included thorough quality assurance of the documentation, with attention to edge cases in tunnel setup workflows. The approach prioritized accuracy and clarity, ensuring that users could configure tunnels correctly and avoid common pitfalls during deployment.
