# Contributing to Caddy UI

Thank you for your interest in contributing! This document explains how to get involved.

## Ways to Contribute

- **Bug reports** — open a GitHub Issue with steps to reproduce
- **Feature requests** — open an Issue describing the use case
- **Pull requests** — bug fixes and small improvements are welcome
- **Documentation** — corrections, clarifications, and examples

---

## Before You Open a PR

1. **Check existing issues and PRs** to avoid duplicate work.
2. For anything beyond a small bug fix, open an Issue first to discuss approach.
3. Keep PRs focused — one concern per PR makes review easier.

## Development Setup

### Prerequisites

- [Go 1.22+](https://go.dev/dl/)
- [Docker](https://docs.docker.com/get-docker/) (for local Caddy instance)
- A running Caddy instance with admin API accessible (default: `http://localhost:2019`)

### Run Locally

```bash
git clone https://github.com/X4Applegate/caddyui.git
cd caddyui

# Start a local Caddy for testing
docker run -d --name caddy-dev \
  -p 2019:2019 \
  caddy:2-alpine caddy run --config "" --adapter ""

# Run CaddyUI
CADDY_ADMIN_URL=http://localhost:2019 \
CADDYUI_DB=/tmp/caddyui-dev.db \
go run ./cmd/caddyui
```

Open http://localhost:8080 and complete first-run setup.

### Project Layout

```
cmd/caddyui/        main(), env vars, startup wiring
internal/auth/      sessions, bcrypt, TOTP
internal/caddy/     admin API client, Caddyfile adapter
internal/db/        SQLite open + migrations
internal/models/    structs and DB queries
internal/server/    all HTTP handlers + background goroutines
web/templates/      Go html/template (one file per page)
web/static/         CSS (Tailwind CDN), icons, PWA files
```

### Templates

Templates use Tailwind CSS loaded from CDN — no build step needed. The `web/embed.go` file embeds everything into the binary at compile time.

- Follow existing code style (no external linters required, just match what's there).
- Add a clear description of what changed and why.
- Reference the related Issue number if applicable (`Closes #123`).
- Keep commits clean — squash WIP commits before opening the PR.
