# Get started with the Amazon SDK for .NET
<a name="net-dg-config"></a>

To use the Amazon SDK for .NET, you need to install your toolchain and configure a number of essential things that your application needs to access Amazon services. These include:
+ An appropriate user account or role
+ Authentication information for that user account or to assume that role
+ Specification of the Amazon Region
+ AWSSDK packages or assemblies

Some of the topics in this section provide information about how to configure these essential things.

Other topics in this section and other sections provide information about more advanced ways that you can configure your project.
