+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Application Overview
+
+CMC Sales is a B2B sales management system for CMC Technologies. The codebase consists of:
+
+- **Legacy CakePHP 1.2.5 application** (2008-era) - Primary business logic
+- **Modern Go API** (in `/go-app/`) - New development using sqlc and Gorilla Mux
+
+**Note**: Documentation also references a Django application that is not present in the current codebase.
+
+## Development Commands
+
+### Docker Development
+```bash
+# Start all services (both CakePHP and Go applications)
+docker compose up
+
+# Start specific services
+docker compose up cmc-php    # CakePHP app only
+docker compose up cmc-go     # Go app only
+docker compose up db         # Database only
+
+# Restore database from backup (get backups via rsync first)
+rsync -avz --progress cmc@sales.cmctechnologies.com.au:~/backups .
+gunzip < backups/backup_*.sql.gz | mariadb -h 127.0.0.1 -u cmc -p cmc
+
+# Access development sites (add to /etc/hosts: 127.0.0.1 cmclocal)
+# http://cmclocal (CakePHP legacy app via nginx)
+# http://localhost:8080 (Go modern app direct access)
+```
+
+### Testing
+```bash
+# CakePHP has minimal test coverage
+# Test files located in /app/tests/
+# Uses SimpleTest framework
+```
+
+### Go Application Development
+```bash
+# Navigate to Go app directory
+cd go-app
+
+# Configure private module access (first time only)
+go env -w GOPRIVATE=code.springupsoftware.com
+
+# Install dependencies and sqlc
+make install
+
+# Generate sqlc code from SQL queries
+make sqlc
+
+# Run the Go server locally
+make run
+
+# Run tests
+make test
+
+# Build binary
+make build
+```
+
+## Architecture
+
+### CakePHP Application (Legacy)
+- **Framework**: CakePHP 1.2.5 (MVC pattern)
+- **PHP Version**: PHP 5 (Ubuntu Lucid 10.04 container)
+- **Location**: `/app/`
+- **Key Directories**:
+  - `app/models/` - ActiveRecord models
+  - `app/controllers/` - Request handlers  
+  - `app/views/` - Templates (.ctp files)
+  - `app/config/` - Configuration including database.php
+  - `app/vendors/` - Third-party libraries (TCPDF for PDFs, PHPExcel)
+  - `app/webroot/` - Public assets and file uploads
+
+### Go Application (Modern)
+- **Framework**: Gorilla Mux (HTTP router)
+- **Database**: sqlc for type-safe SQL queries
+- **Location**: `/go-app/`
+- **Structure**:
+  - `cmd/server/` - Main application entry point
+  - `internal/cmc/handlers/` - HTTP request handlers
+  - `internal/cmc/db/` - Generated sqlc code
+  - `sql/queries/` - SQL query definitions
+  - `sql/schema/` - Database schema
+- **API Base Path**: `/api/v1`
+
+### Database
+- **Engine**: MariaDB
+- **Host**: `db` (Docker service) or `127.0.0.1` locally
+- **Name**: `cmc`
+- **User**: `cmc`
+- **Password**: `xVRQI&cA?7AU=hqJ!%au` (hardcoded in `app/config/database.php`)
+
+## Key Business Entities
+
+- **Customers** - Client companies with ABN validation
+- **Purchase Orders** - Orders with suppliers (revision tracking enabled)
+- **Quotes** - Customer price quotations
+- **Invoices** - Billing documents
+- **Products** - Catalog with categories and options
+- **Shipments** - Logistics and freight management
+- **Jobs** - Project tracking
+- **Documents** - PDF generation via TCPDF
+- **Emails** - Correspondence tracking
+
+## File Storage
+
+- **PDF files**: `/app/webroot/pdf/` (mounted volume)
+- **Attachments**: `/app/webroot/attachments_files/` (mounted volume)
+
+## Critical Considerations
+
+- **Security**: Running on extremely outdated Ubuntu Lucid (10.04) with PHP 5
+- **Database Changes**: Exercise caution - the database may be shared with other applications
+- **CakePHP Conventions**: Uses 2008-era patterns and practices
+- **Authentication**: Basic auth configured via `userpasswd` file
+- **PDF Generation**: Uses TCPDF library in `/app/vendors/tcpdf/`

 # cmc-sales
 
-## Development Docker compose instructions
+## Development Setup
+
+CMC Sales now runs both legacy CakePHP and modern Go applications side by side.
+
+### Quick Start
 
 ``` shell
 git clone git@code.springupsoftware.com:cmc/cmc-sales.git
 cd cmc-sales
+
+# Easy way - use the setup script
+./start-development.sh
+
+# Manual way
 rsync -avz --progress cmc@sales.cmctechnologies.com.au:~/backups .
-docker compose up
-# DB password is in config/database.php because..reasons. 
-# TODO move it to an environment var and rotate it..
+docker compose up --build
 gunzip < backups/backup_*.sql.gz | mariadb -h 127.0.0.1 -u cmc -p cmc
-
-# edit your dev machine /etc/hosts and add
-127.0.0.1	cmclocal
-
-# open up cmclocal in your browser.. hopefully it'll work.
 ```
 
+### Access Applications
+
+**Add to /etc/hosts:**
+```
+127.0.0.1	cmclocal
+```
+
+**Application URLs:**
+- **CakePHP (Legacy)**: http://cmclocal - Original CakePHP 1.2.5 application
+- **Go (Modern)**: http://localhost:8080 - New Go application with HTMX frontend
+- **Database**: localhost:3306 (user: `cmc`, password: see `app/config/database.php`)
+
+### Architecture
+
+- **cmc-php**: Legacy CakePHP application (nginx proxied)
+- **cmc-go**: Modern Go application (direct access on port 8080)
+- **db**: Shared MariaDB database
+- **nginx**: Reverse proxy for CakePHP app
+
+Both applications share the same database, allowing for gradual migration.
+
+### Requirements
+
+- **Go Application**: Requires Go 1.23+ (for latest sqlc)
+  - Alternative: Use `Dockerfile.go.legacy` with Go 1.21 and sqlc v1.26.0
+

-FROM python:3.11-slim AS base

-ENV DEBIAN_FRONTEND=noninteractive
-
-# Install essential system dependencies
-# - build-essential: Required for compiling some Python packages with C extensions.
-# - pkg-config: Helper tool for finding library compilation flags.
-# - default-libmysqlclient-dev: Required for mysqlclient (MySQL/MariaDB adapter).
-#   (Replaced libpq-dev from previous version).
-# - curl: Needed to download the uv installer script.

-# RUN uv pip install --system --no-cache-dir -r requirements.txt
-
-# NOTE: Removed the 'uv pip install .' command below as it caused the
