Developed a documentation feature for the bufbuild/modules repository to enhance reliability and maintainability in multi-instance deployments. The work centered on implementing dynamic hostname templating within buf.md files, replacing hardcoded hostnames with a {{bsrhost}} template variable. This approach leveraged Markdown and template management skills to ensure documentation always reflects the active BSR hostname, reducing manual updates and minimizing misconfiguration risks when switching between BSR instances. The changes were closely aligned with core BSR updates to support runtime hostname resolution, resulting in more flexible, accurate documentation and streamlined onboarding for teams working across multiple modules and deployment environments.
