+## Parameter Structure Names
+
+It is possible to rename the arguments a generated function would use.
+For example, if you had a generated function called `FindWriter`
+which used a generated name of `FindWriterParams`, you can choose to rename
+this:
+
+```yaml
+version: "2"
+sql:
+  - engine: postgresql
+    queries: query.sql
+    schema: query.sql
+overrides:
+  go:
+    rename:
+      FindWriterParams: SomeOtherNameParams
+```
+
+The target name must be unique, and even if multiple structures would
+have the same fields, there will be a conflict.
+
 ## Limitations
 
 Rename mappings apply to an entire package. Therefore, a column named `foo` and
-a table name `foo` can't map to different rename values.
\ No newline at end of file
+a table name `foo` can't map to different rename values.
