+
+## 📦 Shared Renovate configuration
+
+This repository hosts the organization's shared [Renovate][renovate] preset, inherited by every Gitify repository.
+
+| File                   | Purpose                                                                                         |
+| ---------------------- | ----------------------------------------------------------------------------------------------- |
+| `default.json`         | Baseline preset every repository inherits via `extends: ["github>gitify-app/.github"]`.         |
+| `renovate-config.json` | Onboarding entry point (`extends: ["./default"]`); Renovate suggests it automatically for new repositories. |
+
+## 🔗 Inheriting and extending
+
+A repository inherits the baseline by extending the shared preset, then adds its own configuration after it. Repository-level settings and later `packageRules` take precedence:
+
+```jsonc
+{
+  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
+  "extends": ["github>gitify-app/.github"],
+  "packageRules": [
+    { "description": "repo-specific rule" }
+  ]
+}
+```
+
+## 🛠️ Policy
+
+- 🗓️ Weekly updates, with grouped Vite+ and GitHub Actions updates.
+- 🟢 Node runtime tracks LTS only; `@types/node` majors are handled per repository.
+- 🛡️ OSV vulnerability alerts on; no automerge in the baseline.
+
+## ✅ Validation
+
+`default.json`, `renovate-config.json`, and any other preset files are validated with `renovate-config-validator --strict` by [`.github/workflows/renovate-config-validator.yml`](.github/workflows/renovate-config-validator.yml). Consumer repositories call the same reusable workflow to validate their own `renovate.json`.
