+# Support
+
+ditto.site is an open-source project maintained on a best-effort basis.
+
+## Questions
+
+Use GitHub issues for concrete questions that are tied to this repository:
+
+- setup problems that reproduce from a clean checkout,
+- CLI, REST, MCP, or worker behavior,
+- compiler output that looks wrong for a public, reproducible URL,
+- documentation gaps that block a contributor.
+
+Before opening an issue, search existing issues and include the command, URL,
+options, Node version, operating system, and any run artifact or validation
+report that helps reproduce the problem.
+
+## Bugs And Feature Requests
+
+Use the GitHub issue templates:
+
+- Bug reports: [new bug report](https://github.com/ion-design/ditto.site/issues/new?template=bug_report.md)
+- Feature requests: [new feature request](https://github.com/ion-design/ditto.site/issues/new?template=feature_request.md)
+
+If a report involves a specific site, include only public URLs and scrub any
+private credentials, cookies, internal hostnames, or proprietary content.
+
+## Security
+
+Do not open public issues for vulnerabilities. Follow [SECURITY.md](SECURITY.md)
+and report privately through GitHub security advisories or email.
+
+## Maintainer Expectations
+
+There is no guaranteed response time or support SLA. Clear reproduction steps,
+small examples, and focused pull requests are the fastest path to resolution.
