+# func-toolkit
+
 The func-toolkit includes several useful function combinator and utilities. The compinator provided by the func-toolkit can use any iterable object. func-toolkit provides all of these without any dependencies.
 
 ## How to use
 
-### Example: compose
-``` js
-const $ = require('func-toolkit');
+Most examples can find on test code.
+
+### Example: all
+
+```ts
+import { all } from "func-toolkit";
+
+const data = [2, 10, 4, 6];
+const isAllEven = all(data, element => element % 2 == 0);
+```
+
+### Example: andThen
+
+```ts
+import { andThen } from "func-toolkit";
 
 function f(x) {
   return 2 * x;
