Source: https://github.com/stevekoeniger/doclingsharp/blob/master/README.md

Installs the DoclingSharp library into your .NET project using the NuGet package manager. Ensure you have .NET 8+ and access to the NuGet feed.

```bash
dotnet add package DoclingSharp
```

### Manual DoclingClient and DocumentChunker Initialization

Source: https://github.com/stevekoeniger/doclingsharp/blob/master/README.md

Provides an example of manually initializing DoclingClient and DocumentChunker instances with explicit options and an HttpClientFactory. This approach is useful for scenarios where automatic DI is not preferred or available.

```csharp
var options = new DoclingOptions
{
    DoclingAddress = new Uri("http://localhost:5001"),
    ChunkMaxCharacters = 2048,
    ChunkCharacterOverlap = 128
};

var httpClientFactory = ...; // get via DI or manually
var doclingClient = new DoclingClient(httpClientFactory, Options.Create(options));
var doclingClient = new DoclingClient(httpClientFactory, Options.Create(options));
var documentChunker = new DocumentChunker(options);

var file = File.OpenRead("example.pdf");
var result = await doclingClient.ExtractDocumentContentAsync(file);
var chunks = doclingClient.ChunkDocument(result.Markdown);
```

### Configure DoclingSharp Services in .NET

Source: https://github.com/stevekoeniger/doclingsharp/blob/master/README.md

Configures the DoclingSharp services, including DoclingClient and DocumentChunker, by registering them with the .NET dependency injection container. This setup requires specifying the Docling API address and chunking parameters.

```csharp
builder.Services.AddDocling(c =>
{
    c.DoclingAddress = new Uri("http://localhost:5001");
    c.ChunkMaxCharacters = 2048;
    c.ChunkCharacterOverlap = 128;
});
```

### Extract Document Content with DoclingClient

Source: https://github.com/stevekoeniger/doclingsharp/blob/master/README.md

Demonstrates how to use the DoclingClient to extract content from an uploaded IFormFile. The extracted content, including Markdown, is then processed further.

```csharp
// Extract content from an uploaded IFormFile
var result = await _doclingClient.ExtractDocumentContentAsync(file);

// Split the content into chunks for embedding or further processing
var documentChunks = _documentChunker.ChunkDocument(result.Markdown);

// Pass the chunks to your embedding engine
```
