+## Overview
+
+This plugin sorts members of your classes, interfaces, and type aliases.
+
+```ts
+// Before
+class MyClass {
+	c: string;
+	a(): void {}
+	b: number;
+	constructor() {}
+}
+
+// After
+class MyClass {
+	b: number;
+	c: string;
+	constructor() {}
+	a(): void {}
+}
+```
+
+The order respects default order of [`@typescript-eslint/member-ordering`](https://typescript-eslint.io/rules/member-ordering/#default-configuration)
