 # Azure virtual machine extensions and features
-Extensions are small applications that provide post-deployment configuration and automation on Azure VMs. The Azure platform hosts many extensions covering VM configuration, monitoring, security, and utility applications. Publishers take an application, wrap it into an extension, and simplify the installation. All you need to do is provide mandatory parameters.

 ## How can I find what extensions are available?
-You can view available extensions by selecting a VM, the selecting **Extensions** in the left menu. To pull a full list of extensions, see [Discovering VM Extensions for Linux](features-linux.md) and [Discovering VM Extensions for Windows](features-windows.md).

 ## How can I install an extension?
-Azure VM extensions can be managed using the Azure CLI, PowerShell, Resource Manager templates, and the Azure portal. To try an extension, go to the Azure portal, select the Custom Script Extension, then pass in a command or script to run the extension.

 For more information, see [Windows Custom Script Extension](custom-script-windows.md) and [Linux Custom Script Extension](custom-script-linux.md).
 
 ## How do I manage extension application lifecycle?
-You do not need to connect to a VM directly to install or delete an extension. The Azure extension lifecycle is managed outside of the VM and integrated into the Azure platform.

 ## Anything else I should be thinking about for extensions?
-Some individual VM extension applications may have their own environmental prerequisites, such as access to an endpoint. Each extension has an article that explains any pre-requisites, including which operating systems are supported.
