+Azure
+===============
+
+To deploy kubespray on [Azure](https://azure.microsoft.com) uncomment the `cloud_provider` option in `group_vars/all.yml` and set it to `'azure'`.
+
+All your instances are required to run in a resource group and a routing table has to be attached to the subnet your instances are in.
+
+Not all features are supported yet though, for a list of the current status have a look [here](https://github.com/colemickens/azure-kubernetes-status)
+
+### Parameters

+Before creating the instances you must first set the `azure_` variables in the `group_vars/all.yml` file.
+
+All of the values can be retrieved using the azure cli tool which can be downloaded here: https://docs.microsoft.com/en-gb/azure/xplat-cli-install
+After installation you have to run `azure login` to get access to your account.
