+# e-com.plus Cloud Commerce Configuration
+
+## Git Staging Rules
+
+**IMPORTANT**: When performing git add and commit operations:
+- NEVER stage package.json and lock files (package-lock.json, yarn.lock, pnpm-lock.yaml) unless explicitly requested
+- Exception: Only stage dependency files when the user specifically asks to "add dependency files" or similar explicit instruction
+- Always check what files are being staged before committing
+- Ask for confirmation if dependency files would be included unintentionally
+
+## Project Context
+
+Complete platform on top of headless commerce APIs. High performant Astro + Vue storefront with built-in CMS. Integrations for payments, shipping, ERPs, CRMs and others. Truly extensible event-driven and serverless architecture. Easy and cheap deploy to Firebase.
+
+This project includes multiple store submodules with dependencies that frequently change during development.
