+#  Certbot with Stackit DNS Plugin (Docker Compose)
+
+- Custom Docker image: Based on certbot/certbot, with the Stackit DNS plugin installed.
+- Docker Compose service to request wildcard certificates.
+
+---
+## 📂 Certificate File Structure
+
+```
+./letsencrypt/live/<your-domain>/
+├── cert.pem            # Your domain’s certificate
+├── chain.pem           # The Let's Encrypt chain
+├── fullchain.pem       # cert.pem + chain.pem (what you usually use)
+├── privkey.pem         # Your private key
+```
+
+
+## 🛠️ Setup Instructions
+
+
+### 1. Create a file named `stackit.ini` in the root directory:
+
+⚠️️️ Make sure the file is secure: (`chmod 600 stackit.ini`)
+```
+dns_stackit_auth_token = YOUR_API_TOKEN
+dns_stackit_project_id = YOUR_PROJECT_ID
+```
+
+### 2. Set domain in `.env` file
+```
+DOMAIN=example.com
+WILDCARD=*.example.com
+```
+
+### 3. Run Certbot
+```
+docker compose up certbot
+```
+
+### 4. Cert permission
+
+The certs and the live folder will be `root:root`, in order to access them with your user
+```bash
+sudo chown -R $(id -u):$(id -g) ./letsencrypt
+```
