+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Cloud Apache Container (CAC) is a Docker-based PHP web hosting environment that supports multiple PHP versions (7.4 through 8.4) with Apache, designed for both local development and production deployment.
+
+## Common Development Commands
+
+### Local Development Setup
+```bash
+# Quick start with automated setup (creates helper scripts)
+./local-dev.sh -n local-dev
+
+# With specific PHP version
+./local-dev.sh -n myproject -a 84  # PHP 8.4
+
+# Helper scripts created by local-dev.sh:
+./instance_start    # Start container
+./instance_stop     # Stop container
+./instance_logs     # Tail Apache logs
+./instance_db_info  # Show MySQL credentials
+```
+
+### Building and Testing
+```bash
+# Build container locally
+docker build -t cac:latest .
+
+# Build with specific PHP version
+docker build --build-arg PHP_VER=83 -t cac:php83 .
+
+# Run container manually
+docker run -d -p 80:80 -p 443:443 \
+  -e PHPVER=83 -e environment=DEV \
+  -e uid=$(id -u) -e user=$(whoami) -e domain=localhost \
+  -v"$(pwd)/user":/home/$(whoami) \
+  --name test-container cac:latest
+```
+
+### Server Deployment
+- Production git directory: `/root/whp`
+- After `git pull`, sync web files: `rsync -av web-files/ /docker/whp/web/`
+
+## Architecture and Key Components
+
+### Directory Structure
+- `/scripts/` - Container setup scripts (entrypoint, PHP installers, vhost creation)
+- `/config/` - Apache and PHP configuration files
+- `/web-files/` - Default web content (ping endpoint)
+- `/.gitea/workflows/` - CI/CD pipeline for multi-PHP version builds
+
+### Container Behavior
+1. **Entrypoint Flow** (`scripts/entrypoint.sh`):
+   - Creates user with specified UID
+   - Sets up directory structure
+   - Configures Apache vhost based on environment variables
+   - In DEV mode: starts MariaDB and Memcached
+   - Starts Apache and PHP-FPM
+
+2. **Environment Modes**:
+   - **DEV** (`environment=DEV`): Local database, memcached, automatic backups
+   - **PROD** (default): Expects external database/cache services
+
+3. **PHP Version Management**:
+   - Controlled via `PHPVER` environment variable (74, 80, 81, 82, 83, 84)
+   - Each version has dedicated install script in `/scripts/`
+   - PHP-FPM configuration dynamically created based on version
+
+### Key Environment Variables
+- `uid` (required): User ID for file permissions
+- `user` (required): Username for container user
+- `domain` (required): Primary domain for Apache vhost
+- `serveralias`: Additional domains (comma-separated)
+- `PHPVER`: PHP version to use (default: 83)
+- `environment`: DEV or PROD mode
+
+## Important Technical Details
+
+1. **Health Check**: Available at `/ping` endpoint
+2. **Logs Location**: `/home/$user/logs/apache/` and `/home/$user/logs/php-fpm/`
+3. **Database Backups** (DEV mode): Every 15 minutes to `/home/$user/_db_backups/`
+4. **Log Rotation**: Compress after 3 days, delete after 7 days
+5. **SSL**: Self-signed certificate auto-generated, proper SSL configured
+6. **WordPress**: WP-CLI pre-installed for WordPress development
