+# Version Alignment Policy
+
+> **Disclaimer:** cpp-linter does **not** develop or maintain LLVM / Clang tools. We only
+> pre-build and repackage upstream LLVM releases for easier installation. We do **not** fix
+> bugs, add features, or backport patches to any LLVM version — those are the responsibility
+> of the [LLVM project](https://github.com/llvm/llvm-project).
+
+We provide pre-built static binaries, Docker images, and Python wheels for **LLVM 11 through
+the latest stable release**. The latest 3 major versions receive full CI testing coverage.
+
+Older versions may be dropped over time as they become difficult to build on current platforms.
+Version-specific issues in dropped versions will be closed as `wontfix`.

+
+## FAQ
+
+**Q: Do you fix bugs in clang-tidy or clang-format?**
+
+No. Please report tool bugs to the [LLVM project](https://github.com/llvm/llvm-project/issues).
+If a download is broken or a binary is missing, report that to us.
+
+**Q: Which default version does `cpp-linter-action` use?**
+
+Currently **LLVM 20** (the middle of the latest 3 major versions).
+
+**Q: Need a version we no longer package?**
+
+You can fork our build repositories and build it yourself. Start a
+[discussion](https://github.com/orgs/cpp-linter/discussions) if you think others need it too.
