I'll help you add documentation by creating a README.md file and adding some package-level documentation. Let's start with the main README:

# BYOM Gateway

BYOM Gateway is a Go-based service that manages user-host associations with a secure REST API.

## Features

- RESTful API for user-host management
- SQLite database with WAL mode for data persistence
- Secure by default with comprehensive security middleware
- Structured logging and request tracing
- Configuration via YAML
- Basic authentication support

## Prerequisites

- Go 1.19 or higher
- SQLite 3

## Quick Start

1. Clone the repository:

bash git clone git.linuxforward.com/byom/byom-gateway cd byom-gateway

2. Copy the sample config:

bash cp config.sample.yaml config.yaml

3. Build and run:

bash go build ./byom-gateway

## Configuration

Configuration is managed through a YAML file. Example configuration:

yaml server: port: "8080" tls:

database: file: "./data/dev.db" log_mode: true max_open_conns: 10 max_idle_conns: 5 conn_max_lifetime: 3600 pragma:

- "journal_mode=WAL"
- "busy_timeout=5000"
- "foreign_keys=ON"
