+# CLAUDE.md
+
+This is a public open-source package maintained under github.com/dmstr.
+
+## Language policy
+
+**Everything in this repository is in English** — commit messages, code,
+comments, and documentation. Do not write German here, even though related
+company/customer projects (e.g. the consuming application) use German. These
+packages are public and English-only.
+
+## Testing
+
+PHPUnit (^12). Run locally with the bundled CLI-only Docker Compose
+(no host PHP required):
+
+    docker compose run --rm php
+
+This installs dependencies and runs `vendor/bin/phpunit`. The same runs in CI
+via `.github/workflows/tests.yml`.
+
+## Requirements
+
+PHP >= 8.4.
