 ### Bulk Updates
 Bulk updates are supported. To execute multipe statements in one HTTP call, simply include the statements in the JSON array:
 
-    curl -L -XPOST 'localhost:4001/db?pretty' -H "Content-Type: application/json" -d '[
-        "INSERT INTO foo(name) VALUES(\"fiona\")",
-        "INSERT INTO foo(name) VALUES(\"sinead\")"
-    ]'

 ### Transactions
 Transactions are supported. To execute statements within a transaction, add `transaction` to the URL. An example of the above operation executed within a transaction is shown below.
 
-    curl -L -XPOST 'localhost:4001/db?pretty&transaction' -H "Content-Type: application/json" -d '[
-        "INSERT INTO foo(name) VALUES(\"fiona\")",
-        "INSERT INTO foo(name) VALUES(\"sinead\")""

+        \"INSERT INTO foo(name) VALUES('fiona')\",
+        \"INSERT INTO foo(name) VALUES('sinead')\"
+    ]"
 
 When a transaction takes place either both statements will succeed, or neither. Performance is *much, much* better if multiple SQL INSERTs or UPDATEs are executed via a transaction. Note the execution ceases the moment any single query results in an error.

 ### Handling Errors
 If an error occurs while processing a statement, it will be marked as such in the response. For example.
