+# Contributing
+
+Thanks for taking the time to improve this package.
+
+## Local setup
+
+```bash
+npm install
+npm run typecheck
+npm test
+npm run build
+```
+
+## Pull requests
+
+Please keep changes focused and include tests for behavior changes. Small API improvements are welcome when they keep the package predictable, typed, and easy to use in both Node and browser-oriented tooling.
+
+Before opening a pull request, run:
+
+```bash
+npm run typecheck
+npm test
+npm run build
+```
+
+## Issues
+
+When reporting a bug, include:
+
+- the package version;
+- the input that failed;
+- the expected output;
+- the actual output or diagnostic code.
+
+Please avoid broad feature requests that would turn the package into a large framework. These utilities are intentionally small and focused.

+# Security Policy
+
+## Reporting a Vulnerability
+
+If you find a security issue, please report it privately when GitHub security advisories are available for this repository. If private advisories are not available, open a minimal issue that describes the affected package and version without publishing exploit details.
+
+Please include:
+
+- the affected package and version;
+- the smallest input or scenario needed to understand the issue;
+- the impact you believe it has;
+- whether the issue affects Node, browsers, or both.
+
+These packages are small developer utilities, but parser and renderer bugs can still matter. Reports about denial-of-service behavior, unsafe output, or misleading validation are welcome.
