 This export type is useful when using kebab (param) cased class names since variables with a `-` are not valid variables and will produce invalid types or when a class name is a TypeScript keyword (eg: `while` or `delete`). Additionally, the `Styles` and `ClassNames` types are exported which can be useful for properly typing variables, functions, etc. when working with dynamic class names.
 
+### `--exportTypeName`
+
+- **Type**: `string`
+- **Default**: `"ClassNames"`
+- **Example**: `tsm src --exportType default --exportTypeName ClassesType`
+
+Customize the type name exported in the generated file when `--exportType` is set to `"default"`.
+Only default exports are affected by this command. This example will change the export type line to:
+
+```typescript
+export type ClassesType = keyof Styles;
+```
+
+### `--exportTypeInterface`
+
+- **Type**: `string`
+- **Default**: `"Styles"`
+- **Example**: `tsm src --exportType default --exportTypeInterface IStyles`
+
+Customize the interface name exported in the generated file when `--exportType` is set to `"default"`.
+Only default exports are affected by this command. This example will change the export interface line to:
+
+```typescript
+export interface IStyles {
+  // ...
+}
