+Run **Remove_comments.sql**  to create  a procedure. 
+Strip and remove all comments from your T-SQL query by using _dbo.remove_comments_ procedure 
 
-1. Run the support files
+``` sql
+--  Run procedure dbo.remove_comments
 
-Run **helper_fun.sql** helper file, that will create a sample data tables and example procedure.
-In addition, run a **remove_comments.sql** file to create a procedure with stripping and removing  all the comments from your T-SQL query.
+EXEC dbo.remove_comments
+   @procedure_name = N'dbo.MySample_procedure'
 
-2. Removing comments from T-SQL Query
+```
 
-Strip and remove all comments from your T-SQL query by using _dbo.remove_comments_ procedure.
 
-``` sql
-# Run procedure dbo.remove_comments
+# Start with Data Lineage on T-SQL
+
+Run **TSQL_data_lineage.sql**  file to create  a lineage procedure. This script includes the removal of comments and special characters and creates the data lineage.
 
-EXEC dbo.remove_comments
-   @procedure_name = N'sql_sample_procedure'
 
+```sql
+-- Get your query:
+declare @test_query VARCHAR(8000) = '
+
+SELECT 
+    s.[BusinessEntityID]
+    ,p.[Title]
+    ,p.[FirstName]
+    ,p.[MiddleName]

+    ,s.[SalesYTD]
+    ,s.[SalesLastYear]
+	,( SELECT GETDATE() ) AS DateNow
+	,( select count(*)  FROM [AdventureWorks2014].sales.[SalesPerson] ) as totalSales
+
+FROM [AdventureWorks2014].sales.[SalesPerson] s
+    LEFT JOIN [AdventureWorks2014].[HumanResources].[Employee] e 
+    ON e.[BusinessEntityID] = s.[BusinessEntityID]
+	INNER JOIN [AdventureWorks2014].[Person].[Person] AS p
+	ON p.[BusinessEntityID] = s.[BusinessEntityID]
+
+'
+
+-- And run the procedure with single input parameter
+EXEC dbo.TSQL_data_lineage 
+  @InputQuery = @test_query
 ```
