+# ARM Test Cases
+This folder holds the test cases for **Azure Resource Manager (ARM)**.  
+
+## Additional Docs
+No Additional information is needed for this test case.
+
+## Good Test Cases
+The test cases denoted: `LANGUAGE_good_FILE.EXTENSION` are all valid, and should pass successfully when linted.
+- **Note:** They are linted utilizing the default linter rules.
+
+## Bad Test Cases
+The test cases denoted: `LANGUAGE_bad_FILE.EXTENSION` are **NOT** valid, and should trigger errors when linted.
+- **Note:** They are linted utilizing the default linter rules.
