+# Renovate Showcase
+
+Demonstrates usage of [Renovate](https://www.whitesourcesoftware.com/free-developer-tools/renovate/), a tool that automatically updates dependencies in your code.
+
+Reference presentation: [https://slides.by.vincent.mahn.ke/#/10](https://slides.by.vincent.mahn.ke/#/10)
+
+## Scenarios
+
+This repository contains 4 different scenarios:
+
+### 1. [Setup](./1-setup)
+Basic setup showing Renovate can be run with nothing to update.
+
+### 2. [Dockerfile with Dry Run](./2-dockerfile-dry-run)
+Shows how Renovate detects outdated versions in a Dockerfile and how a dry run would create a pull request.
+
+### 3. [Dockerfile with Renovate Config](./3-dockerfile-with-config)
+Same as scenario 2, but with a Renovate configuration that ignores the version update.
+
+### 4. [Regex Node Version Update](./4-regex-node-version)
+Uses Renovate's regex manager to find and update Node.js versions in documentation via regular expressions.
+
+## How to Use
+
+Navigate into each scenario folder and follow the README instructions:
+
+```bash
+cd 1-setup
+cat README.md
+```
+
+Each folder is independent and can be tested separately.
