+
+This is a Renovate config commonly inherited by Agaroot products.
+
+Use this setting to keep up with updates to the library and maintain high code quality.
+
+## 👏 Getting Started
+
+### 1. Install Renovate App
+
+Install the [Renovate App](https://github.com/apps/renovate) in the repository.
+
+### 2. Allow auto merge
+
+Allow [automatic merging](https://docs.github.com/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/automatically-merging-a-pull-request) of repositories to make Renovate auto-merge work.
+
+Updates below the minor version will be merged automatically, so be sure to use [branch protection rules](https://docs.github.com/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/managing-a-branch-protection-rule) accordingly.
+
+### 3. Install Auto Approve Bot
+
+Install the [Approve App](https://github.com/apps/renovate-approve) that automatically approves pull requests in the repository.
+
+If merging a pull request requires the approval of two people, install an additional [Approve2 App](https://github.com/apps/renovate-approve-2) in the repository.
+
+### 4. Configure Renovate
+
+Create a Renovate configuration file (`renovate.json`), and add `github>agaroot-technologies/renovate-config` to the extends property.
+
+```json
+{
+  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
+  "extends": [
+    "github>agaroot-technologies/renovate-config"
+  ]
+}
+```
+
+If additional settings are required, modify the configuration accordingly.
+
+Check the [Renovate documentation](https://docs.renovatebot.com/configuration-options/) for configuration details.
