+Using Azure for LetsEncrypt domain verification
+
+Guide for using Azure for LetsEncrypt domain verification.
+
+Prerequisites:
+- Azure CLI tools installed - see https://docs.microsoft.com/en-us/cli/azure/install-azure-cli
+- Logged in with azure-cli - i.e. azure login
+
+The dns_add_azure and dns_del_azure scripts assume that the following
+environment variables are added to the configuration file:
+
+- AZURE_RESOURCE_GROUP - the name of the resource group that contains the DNS zone 
+- AZURE_ZONE_ID - the name of the DNS zone 
+- AZURE_SUBSCRIPTION_ID - the name or ID of the subscription that AZURE_RESOURCE_GROUP is part of
+
+Each of these variables can be included in the .getssl.cfg, e.g:
+
+export AZURE_RESOURCE_GROUP=my-resource-group
+export AZURE_ZONE_ID=example.com
+export AZURE_SUBSCRIPTION_ID=my-azure-subscriptin 
+
