## Quick Start Examples

### JavaScript/TypeScript
```javascript
import { HCFSClient, Context } from '@hcfs/sdk';

const client = new HCFSClient({
  baseUrl: 'https://api.hcfs.dev/v1',
  apiKey: 'your-api-key'
});

const context = new Context({
  path: '/docs/readme',
  content: 'Hello, HCFS!',
  summary: 'Getting started'
});

const created = await client.createContext(context);
console.log(`Created context: ${created.id}`);
```

### Go
```go
import "github.com/hcfs/hcfs-go"

client := hcfs.NewClient(&hcfs.Config{
    BaseURL: "https://api.hcfs.dev/v1",
    APIKey:  "your-api-key",
})

ctx := &hcfs.Context{
    Path:    "/docs/readme",
    Content: "Hello, HCFS!",
    Summary: "Getting started",
}

created, err := client.CreateContext(context.Background(), ctx)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("Created context: %d\n", created.ID)
```

### Rust
```rust
use hcfs_sdk::{Client, Context, Config};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = Config::new("https://api.hcfs.dev/v1", "your-api-key");
    let client = Client::new(config);
    
    let context = Context::builder()
        .path("/docs/readme")
        .content("Hello, HCFS!")
        .summary("Getting started")
        .build()?;
    
    let created = client.create_context(context).await?;
    println!("Created context: {}", created.id);
    Ok(())
}
```

### Java
```java
import dev.hcfs.sdk.HCFSClient;
import dev.hcfs.sdk.Context;
import dev.hcfs.sdk.Config;

public class Example {
    public static void main(String[] args) {
        Config config = Config.builder()
            .baseUrl("https://api.hcfs.dev/v1")
            .apiKey("your-api-key")
            .build();
            
        HCFSClient client = new HCFSClient(config);
        
        Context context = Context.builder()
            .path("/docs/readme")
            .content("Hello, HCFS!")
            .summary("Getting started")
            .build();
        
        Context created = client.createContext(context).block();
        System.out.println("Created context: " + created.getId());
    }
}
```

### C#
```csharp
using HCFS.SDK;

var config = new HCFSConfig
{
    BaseUrl = "https://api.hcfs.dev/v1",
    ApiKey = "your-api-key"
};

using var client = new HCFSClient(config);

var context = new Context
{
    Path = "/docs/readme",
    Content = "Hello, HCFS!",
    Summary = "Getting started"
};

var created = await client.CreateContextAsync(context);
Console.WriteLine($"Created context: {created.Id}");
```
