Step by Step

Select a region near to yourself then select Create.
Create a Web App
In the Resource group browse screen select your new resource group.
In the popout screen for your resource group click the + Create button.
Search Web App and select the resulting option labeled Web App then click Create.
Select your Resource Group created in the previous step.

Click Review + create then click Create on the subsequent page. The portal will inform you that deployment is in progress and updates automatically once the deployment is complete.
Review the deployed resource
Once the deployment is complete you can click Go to resource. Otherwise you can find your resource group from the main page and find the App Service resource within it.
From your App Service resource window in the Overview tab select Browse from along the header.
This will open a new tab with your deployed resource. Adjust the URL by appending /swagger.

Click + New application setting and enter the name NON_ZERO_VALUE and the value day. Click OK then click Save at the top.

Congratulations on a non-zero day!
