 attribute). One last thing to note is the `buffer.write!` at the end of the

+## Insert Strategies
+
+Multisert defaults to using `INSERT INTO` on `#write!`, but you can set the
+insert strategy to `REPLACE INTO` or `INSERT IGNORE`:
+
+```ruby
+buffer = Multisert.new
+#=> would use INSERT INTO on #write! by default
+
+buffer.insert_strategy = :replace
+#=> would now use REPLACE INTO on #write!
+
+buffer.insert_strategy = :ignore
+#=> would now use INSERT IGNORE on #write!
+```
