+## Defender External Attack Surface Management (EASM)
+
+I use this [Azure service](https://azure.microsoft.com/en-us/pricing/details/defender-external-attack-surface-management/) to directly query the ISG (Intelligent Security Graph) to get the domains of Microsoft's subsidiaries. They are saved in a file called `Microsoft Domains Extra.txt` at the root of this repository. They are not manually verified by me like the main list.

 ## Automated GitHub Workflow
 
-The domain list is [checked](https://github.com/HotCakeX/MicrosoftDomains/actions/workflows/Duplicate%20and%20empty%20lines%20removal.yml) upon changes for duplicate entries and empty lines, and if any are found, they will be removed.
+The [GitHub action](https://github.com/HotCakeX/MicrosoftDomains/actions/workflows/Duplicate%20and%20empty%20lines%20removal.yml) runs every time there is a push in this repository, it makes sure:
+
+* There are no empty lines in the lists
+* There are no entries in the lists that start with `xn--`
+* The lists have no duplicate entires
+* The `Microsoft Domains Extra.txt` does not include any domain that already exists in `Microsoft Domains.txt`
+* There are no entries with non-alphanumeric characters
