If you are not familiar with creating Azure resources, you may wish to follow the step-by-step guide for [creating an Event Hub using the Azure portal](https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-create).  There, you can also find detailed instructions for using the Azure CLI, Azure PowerShell, or Azure Resource Manager (ARM) templates to create an Event Hub.
