Feel free to swap the enchantment to MySQL by simply unraveling a line in the mystical `compose.yaml` file.
+
+### ✨ Project Structure
+
+```plaintext
+.
+├── compose.yml          # 🌐 Docker Compose configuration orchestrating the WordPress magic.
+├── .env                 # 🗝️ Environment file holding configuration secrets for MySQL/MariaDB.
+├── nginx/               # 🌐 Nginx configuration directory, shaping the entrance to the WordPress realm.
+│  └─ default.conf       # 🖌️ Custom Nginx configuration, optimizing the front-end experience.
+├── wordpress/           # 🌐 WordPress configuration directory, defining the ambiance of the digital space.

+│  └─ init.sql           # 🖌️ MySQL/MariaDB initialization script, creating the enchanted database realm.
+```
+
+### 🎭 `compose.yml` - The Magic Potion
+
+```yaml
+version: '3'
+
+services:
+  nginx:
+    image: nginx:alpine3.18-slim
+    ports:
+      - "80:80"
+    ...
+  wordpress:
+    image: wordpress:latest
+    restart: always
+    ...
+  db:
+    # 🧙‍♀️ MariaDB image supporting both amd64 & arm64 architecture
+    image: mariadb:11.0.3
+    # 🧙‍♂️ If you fancy MySQL, just uncomment the line below
+    # image: mysql:8.1.0
+    ...
+```
+
+### 🚀 Deploy with Docker Spells
+
+```bash
+docker-compose up -d
+```
+
+Watch in awe as a network and a magical volume come to life, deploying the enchanted containers...
+
+```bash
+✔ Network compose-wordpress-mysql_default         Created         0.0s
+✔ Volume "compose-wordpress-mysql_db-data"        Created         0.0s
+✔ Container compose-wordpress-mysql-db-1          Started         0.0s
+✔ Container compose-wordpress-mysql-wordpress-1   Started         0.0s
+✔ Container compose-wordpress-mysql-nginx-1       Started         0.1s
+```
+
+### ✨ Expected Spellbinding Result
+
+Peer into the mystic realm and inspect the port mapping:
+
+```bash
+$ docker-compose ps
+NAME                                  IMAGE                    COMMAND                  SERVICE             CREATED              STATUS              PORTS
+compose-wordpress-mysql-db-1          mariadb:11.0.3           "docker-entrypoint.s…"   db                  About a minute ago   Up About a minute   3306/tcp
+compose-wordpress-mysql-nginx-1       nginx:alpine3.18-slim    "/docker-entrypoint.…"   nginx               About a minute ago   Up About a minute   0.0.0.0:80->80/tcp, :::80->80/tcp
+compose-wordpress-mysql-wordpress-1   wordpress:6.3.1-php8.2   "docker-entrypoint.s…"   wordpress           About a minute ago   Up About a minute   80/tcp
+```
+
+Take a magic carpet ride to `http://localhost:80` in your web browser to witness the enchanting WordPress realm.

+
+### 🛑 Stop the Magic, Remove the Spellbound Containers
+
+```bash
+docker-compose down
+```
+
+To erase all traces of the enchanted WordPress data, including the named volumes:
+
+```bash
+docker-compose down -v
+```
+
+Your WordPress Wonderland with MariaDB or MySQL is now ready for you to shape and mold as you please. 🌟 Let the creativity soar, and may your digital adventures be as boundless as the stars! 🌌
