You can now go to your explainpowershell fork on GitHub. Under Actions, run the 'Deploy Azure Infra' workflow, then the 'Deploy app to Azure' workflow and run `./explainpowershell.helpwriter.ps1 -Force -IsProduction -ResourceGroupName $ResourceGroupName -StorageAccountName $StorageAccountName`. The Url where you can reach your version of the project can be found in the Azure Portal. Go to resource group '`$ResourceGroupName'. Under the storage account resource that was deployed, find the 'Static Website' entry in the menu. It is the Url for 'Primary Endpoint'. Alternatively, you can retrieve it with `az`:

`$myStorageAccountName = '$StorageAccountName'
(az storage account show --name `$myStorageAccountName | convertfrom-json).primaryEndpoints.web
