+This repository contains GroupDocs.Conversion Cloud SDK for .NET source code. This SDK has been developed to help you get started with using our document conversion REST API, allowing to seamlessly convert your documents to any format you need. With this single API, you can convert back and forth between over 50 types of documents and images, including all Microsoft Office and OpenDocument file formats, PDF documents, HTML, CAD, raster images and many more.
 
 ## How to use the SDK
 
 The complete source code is available in this repository folder, you can either directly use it in your project via NuGet package manager. For more details, please visit our [documentation website](https://docs.groupdocs.cloud/display/conversioncloud/Available+SDKs#AvailableSDKs-.NET).
 
-## Dependencies
+### Create an account
+Creating an account is very simple. Go to Dashboard to create a free account.
+We’re using Single Sign On across our websites, therefore, if you already have an account with our services, you can use it to also acccess the [Dashboard](https://dashboard.groupdocs.cloud).
 
-- [Json.NET](https://www.nuget.org/packages/Newtonsoft.Json)
+### Create an API client app
+Before you can make any requests to GroupDocs Cloud API you need to get a Client Id and a Client Secret. This will will be used to invoke GroupDocs Cloud API. You can get it by creating a new [Application](https://dashboard.groupdocs.cloud/applicationsV).
