+# Joomla
+
+## Overview
+
+Joomla is a self-hosted content management system (CMS) for building websites and web applications. This Docker Compose stack deploys Joomla with a MariaDB database, persistent storage, and an external reverse proxy.
+
+## Project Details
+
+-   **Project Repository:** [Joomla](https://www.joomla.org)
+-   **Container Image:** [Docker Hub](https://hub.docker.com/_/joomla)
+-   **Compose Example:** [Official Compose](https://hub.docker.com/_/joomla)
+-   **Documentation:** [Joomla Docs](https://docs.joomla.org)
+-   **Reverse Proxy Port:** `80`
+
+## Getting Started
+
+1. Copy `sample.env` to `.env` and edit the values (especially passwords)
+2. Start the stack: `docker compose up -d`
+3. Open http://localhost:8080 (or your proxy domain) in your browser
+4. If `JOOMLA_ADMIN_*` env vars are set, the installer is skipped and an admin user is created automatically. Otherwise, follow the web setup wizard.
+
+## Environment Variable Notes
+
+### Compose
+-   `VOL_PATH` – base path for persistent data volumes (default: `/data`)
+-   `JOOMLA_PORT` – host port for Joomla (default: `8080`)
+-   `JOOMLA_IMAGE` – Joomla image tag (default: `joomla:5`)
+-   `JOOMLA_RESTART` – container restart policy (default: `unless-stopped`)
+
+### Database
+-   `MARIADB_IMAGE` – MariaDB image tag (default: `mariadb:10.11`)
+-   `MARIADB_ROOT_PASSWORD` – MariaDB root password (required)
+-   `JOOMLA_DB_NAME` – database name (default: `joomla`)
+-   `JOOMLA_DB_USER` – database user (default: `joomla`)
+-   `JOOMLA_DB_PASSWORD` – database user password (required)
+
+### Joomla Auto-Deployment
+-   `JOOMLA_SITE_NAME` – site name displayed in Joomla
+-   `JOOMLA_ADMIN_USER` – full name of the admin user
+-   `JOOMLA_ADMIN_USERNAME` – admin login username (default: `admin`)
+-   `JOOMLA_ADMIN_PASSWORD` – admin password (required, min 12 chars)
+-   `JOOMLA_ADMIN_EMAIL` – admin email address
+
+## Volume Notes
+
+-   `${VOL_PATH:-/data}/joomla/db` – MariaDB data files
+-   `${VOL_PATH:-/data}/joomla/html` – Joomla web root (uploaded files, extensions, custom templates)
+
+## Network Notes
+
+Requires the external `proxy` network for reverse proxy access.
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name joomla-mariadb \
+  -e MARIADB_DATABASE=joomla \
+  -e MARIADB_USER=joomla \
+  -e MARIADB_PASSWORD=ChangeThisPassword \
+  -e MARIADB_ROOT_PASSWORD=ChangeThisRootPassword \
+  -v /data/joomla/db:/var/lib/mysql \
+  mariadb:10.11
+```
+
+```bash
+docker run -d \
+  --name joomla \
+  -p 8080:80 \
+  -e JOOMLA_DB_HOST=mariadb \
+  -e JOOMLA_DB_USER=joomla \
+  -e JOOMLA_DB_PASSWORD=ChangeThisPassword \
+  -e JOOMLA_DB_NAME=joomla \
+  -e JOOMLA_SITE_NAME="My Joomla Site" \
+  -e JOOMLA_ADMIN_USER="Joomla Admin" \
+  -e JOOMLA_ADMIN_USERNAME=admin \
+  -e JOOMLA_ADMIN_PASSWORD=ChangeThisPassword \
+  -e JOOMLA_ADMIN_EMAIL=admin@example.com \
+  -v /data/joomla/html:/var/www/html \
+  --link joomla-mariadb:mariadb \
+  joomla:5
+```
+
+## Additional Notes / Gotchas
+
+-   Setting `JOOMLA_ADMIN_*` env vars enables auto-deployment and skips the browser setup wizard. Remove them to run the wizard manually.
+-   Admin password must be at least 12 characters long.
+-   The `html` volume persists uploaded files and installed extensions. Back it up before major Joomla upgrades.
+-   For SMTP configuration, add `JOOMLA_SMTP_HOST` and `JOOMLA_SMTP_HOST_PORT` environment variables.
