+# Use this below method to create azure service principal 
+
+The quickest way and easiest way to create this Service Principal is to use Azure CLI and issue the command: 
+
+```sh
+az ad sp create-for-rbac \
+    --name "myAzureServiceGitHubConnection" \
+    --role contributor \
+    --scopes /subscriptions/{subscription-ID}/resourceGroups/{RG-name} \
+    --sdk-auth 
+```
+
+# Execute below powershell commands in Azure to collect Service Principal information 
+
+To store the information inside a GitHub Actions secret, it needs to be stored within a JSON format.  We can run this PowerShell subscription to collect all the information you will need for GitHub and in the form that GitHub needs.
+
+
+```sh
+$ServicePrincipalName = "MyGithubActionsConnection"
+$AzSubscriptionName = "production"
+
+Connect-AzureAD
+
+$Subscription = (Get-AzSubscription -SubscriptionName $AzSubscriptionName)
+$ServicePrincipal = Get-AzADServicePrincipal -DisplayName $ServicePrincipalName
+$AzureADApplication = Get-AzureADApplication -SearchString $ServicePrincipalName
+
+$OutputObject = [PSCustomObject]@{
+    clientId = $ServicePrincipal.AppId
+    clientSecret = (New-AzureADApplicationPasswordCredential -ObjectId $AzureADApplication.ObjectId).Value
+    subscriptionId = $Subscription.Id
+    tenantId = $Subscription.TenantId
+}
+
+$OutputObject | ConvertTo-Json 
+```
+
+
+# Expected output of the above commands and copy as the below mentioned json format to AZURE_CREDENTIALS
+
+Take a copy of the output from the PowerShell query.  This will be stored inside a GitHub Secret for use within your workflows.
+Within the repository where your workflow is, click on Settings > Secrets > Actions and then click on new repository secret.
+
+```sh
+{
+  "clientId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
+  "clientSecret": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
+  "subscriptionId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
+  "tenantId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+}```
