// FLASHSYNC 2.6.0 - INTEGRATION & SETUP GUIDE

## Quick Start

### 1. Basic Server Setup

```gleam
// In src/server.gleam - already created
import mist
import service

pub fn main() {
  service.new()
  |> service.handler(handle_request)
  |> mist.run_service(on: 3000)
}
```

### 2. Using the UI Builder

```gleam
import ui_builder

// Generate complete HTML page
let html = ui_builder.build_html(
  "<p>Your content here</p>",
  "Page Title"
)
```

### 3. Serving Pages

```gleam
import page_content

// Get any page content
let hub_html = page_content.build_page_content("hub")
let tutor_html = page_content.build_page_content("tutor")
```

## Next Steps: API & LLM Integration

### Implement Chat API (TODO)
```gleam
// In server.gleam, expand handle_chat_api
fn handle_chat_api(req: Request(String)) -> Response(String) {
  // 1. Parse request body
  let body = req.body
  
  // 2. Call LLM service (Gemini/GPT-4)
  let response = call_llm(body)
  
  // 3. Return JSON response
}
```

### Implement Upload API (TODO)
```gleam
// Handle file uploads for problem solving
fn handle_upload_api(req: Request(String)) -> Response(String) {
  // 1. Extract file from request
  // 2. Process image (OCR for problems)
  // 3. Send to problem solver
  // 4. Return solution
}
```

### Implement Generate API (TODO)
```gleam
// Generate content (questions, summaries, etc.)
fn handle_generate_api(req: Request(String)) -> Response(String) {
  // 1. Parse generation request
  // 2. Call appropriate generator
  // 3. Return generated content
}
```
