 ## Goal
 Validate service label exists or create new one for SDK release process.
-
-## Step 1: Get Service Label
-Ask user for their service label. If none provided, explain that a valid service label is required for SDK release.
-
-## Step 2: Validate Label
+ 
+## Step 1: Provide Information
+ 
+Provide the following information about the importance of service labels:
+ 
+"Before your SDK is released, your service must have a valid service label in the Azure SDK repositories. Service labels enable automatic owner assignment and notifications across the Azure SDK ecosystem.
+ 
+When properly configured, service labels automatically:
+ 
+- Notify service owners when issues are filed against their SDK
+- Add appropriate reviewers to pull requests
+- Connect code changes to the right team members through CODEOWNERS integration
+ 
+Without a valid service label, the process to identify the correct service owners for issues and code reviews becomes manual and inefficient."
+ 
+## Step 2: Get Service Label
+ 
+Ask user for their service label. If they don't know their service label provide guidance:
+ 
+- Check out the [Common Labels CSV](https://github.com/Azure/azure-sdk-tools/blob/main/tools/github/data/common-labels.csv) file and look for a row whose first column contains your service's product name.
+ 
+If they don't have a service label - go to Step 3 for new service label
+ 
+## Step 3: Validate Label
+ 
 Use `azsdk_check_service_label` to check status:
-
+ 
 - **Exists**: Success - user can proceed with next steps in SDK release process
 - **InReview**: Label pending approval - user can proceed (will be available once merged)
 - **DoesNotExist**: Go to Step 3 to create new label
 - **NotAServiceLabel**: Label exists but it is not a service label - go to Step 3 for new service label
-
-## Step 3: Create New Service Label
+ 
+## Step 4: Create New Service Label
+ 
 If no valid service label exists, guide the user through creating a new one.
-
+ 
 1. **Check existing labels**: Search for related service labels, offer alternatives
 2. **Generate recommendation**: Suggest label name following guidelines:
+   - Should match the service's official product name as described on Service Tree (e.g., "Event Hubs", "Kusto", "Cosmos", etc.)
    - No "Microsoft/Azure" in name
    - Title Case (except short prepositions)
    - Avoid Service Groups: Use "Communication Rooms" instead of "Communication - Rooms"
    - Single label per service
 3. **Get confirmation**: User confirms or modifies suggested name
 4. **Create label**: Use `azsdk_create_service_label` with confirmed name and documentation link given by user
