+### thunk.promise(thunkable)
+
+it transforms `thunkable` value to a promise.
+
+```js
+const thunk = require('thunks').thunk
+
+thunk.promise(function * () {
+  return yield Promise.resolve('Hello')
+}).then(function (res) {
+  console.log(res)
+})
+```
+
 ### thunk.persist(thunkable)
 
 it transforms `thunkable` value to a persist thunk function, which can be called more than once with the same result(like a promise). The new function returns a child thunk function.
