+# Azure DNS Record Set Delete
+This script deletes specific DNS record sets from Azure based on a keyword. It is a valuable tool for managing DNS resources in Azure.
+
+## Usage
+* Modify config.sh to include the correct arguments.
+* Run main.sh: `./run.sh`
+
+## Config.sh
+
+```
+    #!/bin/bash
+
+    #Get the subscription name
+    SUBSCRIPTION_NAME=""
+
+    # Get the resource group name and zone name from the user.
+    RESOURCE_GROUP_NAME=""
+    DNS_ZONE_NAME=""
+
+    # Get the keyword to select the dns record sets.
+    # This should be common string in all the record names you want to delete.
+    # Examples: hpcc, hpcc2, play
+    KEYWORD=""
+
+    # Types of DNS record sets
+    RECORD_TYPES=("A" "TXT")
