Radish is a simple .Net library that allows you to auto-generate HTML-documentation for your REST API on the basis of attributes in the source code. Radish is an acronym that means REST API Documentation In the Source to Html.

PM> Install-Package Radish

• you do not need to create REST API documentation manually;
• you do not need to sync your documentation file with changes in the code, as it needed for other popular generators, like Swagger or ApiBlueprint;
• unlike the ASP.NET Web API Help Page solution, Radish does not require WebHost, Mvc and Razor libraries, and suits for small self-hosting RESTful servers;
• all documentation is a single HTML-page with CSS and JavaScript embedded.

Writing documentation in the source code with Radish looks like:

// Documentation starts here
[Order("pets", 2)]
[Method("GET", "/api/pets/<id>", "pet-get-by-id")]
[MethodTitle("Get pet")]
[MethodDescription("Returns Pet object by specified id.")]
[RequestParameter("id", "Integer", "Id of the Pet")]
[ResponseBodyDescription("Json-serialized Pet object")]
[ResponseBodyExample(@"{""Id"":1, ""AnimalType"":""Cat"",""Name"":""Lisa"",""Breed"":""Turkish Angora"",""Age"":2,""Color"":""White""}")]
[ResponseCode(200, "OK. On successful result.")]
[ResponseCode(404, "Not Found. When pet with specified id was not found.")]
// Documentation ends here

[HttpGet]
[Route("pets/{petId:long}")]
[ResponseType(typeof(Pet))]
public IHttpActionResult GetPet(int petId)
{
	Pet pet = DataBase.Instance.GetPet(petId);
	if (pet == null)
	{
		return this.NotFound(String.Format("Pet with id = {0} not found.", petId));
	}
	return Ok(pet);
}

Radish uses own simple template engine to create HTML documentation page, and you can freely customize its output. Let's take a look on the output documentation examples (example 1, example 2) for this simple demo. Also check the guide how to use Radish.
