-  *How to use Bella.sort?*
+This library provides a function named "stabilize" that you can pass through it an object or array to get back immutable version.
 
-  ```
-  var a = [1, 5, 19, 6, 4, 11, 7, 22, 40, 3, 8];
-  console.log('Array a, default:');
-  console.log(a);
+Here is an example in Node.js:
 
-  console.log('Array a, from lower to higher:');
-  var a1 = Bella.sort(a);
-  console.log(a1);
-  console.log('Array a, descendant:');
-  var a2 = Bella.sort(a, -1);
-  console.log(a2);
+```
+var stabilize = require('bellajs').stabilize;
 
-  var players = [
-      {
-        'name': 'Jerome Nash',
-        'age': 24
-      },
-      {
-        'name': 'Jackson Valdez',
-        'age': 21
-      },
-      {
-        'name': 'Benjamin Cole',
-        'age': 23
-      },
-      {
-        'name': 'Manuel Delgado',
-        'age': 33
-      },
-      {
-        'name': 'Caleb McKinney',
-        'age': 28
-      }
-  ];
+let user = stabilize({
+  name: 'Bob',
+  age: 17
+});
 
-  console.log('\nList of players as it is:');
-  players.forEach(function(item){
-      console.log([item.name, item.age].join(' | '));
-  });
+// user now is immutable
+console.log(user);
 
-  console.log('\nSort by age from young to old:');
-  var players1 = Bella.sort(players, 'age');
-  players1.forEach(function(item){
-      console.log([item.name, item.age].join(' | '));
-  });
+// access the properties with get() or dot
+let name = user.get('name'); // similar to user.name
+console.log(name);
 
-  console.log('\nAnd then reverse them:');
-  var players2 = Bella.sort(players, {age: -1});
-  players2.forEach(function(item){
-      console.log([item.name, item.age].join(' | '));
-  });
+// you can change properties' value with set() method
+// it will return a copy of user with new property
 
-  ```
+let guest = user.set('name', 'Tom');
+console.log(guest.name); // => Tom
 
+// the value of user.name can not be changed
+console.log(user.name); // => Bob
 
+// because it's immutable
+user.name = 'Jerry';
+console.log(user.name); // => Bob
+```
+
+#### Stabilize an object
+
+```
+stabilize(Object o);
+```
+
+Return an immutable object that has 2 methods "set()" and "get()".
+
+Because the returned object is standard object, so you can still use the built-in methods in [Object.prototype](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/prototype) as normal.
+
+##### .get(key)
+
+Return value of specified property.
+
+##### .set(key, value)
+
+Return an new immutable object with new property.
+
+Setter also accepts an object to allow to define many properties at the same time:
+
+```
+let car = stabilize({
+  name: '',
+  speed: 1000,
+  color: 'black'
+});
+
+let tesla = car.set({
+  name: 'Tesla',
+  price: 40000
+});
+
+console.log(tesla);
+```
+
+*tesla* now is a new object with the following properties:
+
+```
+{
+  name: 'Tesla',
+  speed: 1000,
+  color: 'black',
+  price: 40000
+}
+```
+
+
+#### Stabilize an array
+
+```
+stabilize(Array a);
+```
+
+Return an immutable array that has the new methods: *unique*, *first*, *last*, *insert*, *append*, *remove*, *isort* and *ireverse*. All these methods return the immutable data.
+
+Because the returned array is standard array, so you can still use the built-in methods in [Array.prototype](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array) as normal.
+
+
+##### .unique(key)
+
+Return a new array with no duplicate elements.
+
+```
+let a = stabilize([1, 2, 2, 3, 2, 4]);
+let b = a.unique();
+
+console.log(b); // => [ 1, 2, 3, 4 ]
+```
+
+##### .min()
+
+Return the smallest value from an array of numbers.
+
+```
+let a = stabilize([1, 2, 2, 3, 8, 5, 2, 4]);
+let b = a.min();
+
+console.log(b); // => 1
+```
+
+##### .max()
+
+Return the biggest value from an array of numbers.
+
+```
+let a = stabilize([1, 2, 2, 3, 8, 5, 2, 4]);
+let b = a.max();
+
+console.log(b); // => 1
+```
+
+##### .first()
+
+Return the first element from array.
+
+```
+let a = stabilize([1, 2, 2, 3, 2, 4]);
+let b = a.first();
+
+console.log(b); // => 1
+```
+
+##### .last()
+
+Return the last element from array.
+
+```
+let a = stabilize([1, 2, 2, 3, 2, 4]);
+let b = a.last();
+
+console.log(b); // => 4
+```
+
+##### .pick(count)
+
+Extract *count* elements from array in randomly order.
+
+```
+let a = stabilize([1, 2, 2, 3, 2, 4]);
+let b = a.pick(3);
+console.log(b); // output an array of 3 random elements
+```
+
+Without *count*, this method returns a random element.
+
+
+##### .insert(at, element1, element2, ...elementN)
+
+Return a new array with new elements inserted at the position specified by first parameter.
+
+```
+let a = stabilize([1, 2, 3, 4]);
+let b = a.insert(2, 'a');
+
+console.log(b); // => [ 1, 2, 'a', 3, 4 ]
+```
+
+##### .append(element1, element2, ...elementN)
+
+Return a new array with new elements added at the end.
+
+```
+let a = stabilize([1, 2, 3, 4]);
+let b = a.append(5, 6, 7);
+
+console.log(b); // => [ 1, 2, 3, 4, 5, 6, 7 ]
+```
+
+##### .remove(start, count)
+
+Return a new array with *count* elements deleted beginning at *start*:
+
+```
+let a = stabilize([1, 2, 3, 4, 5, 6]);
+let b = a.remove(3, 2); // remove 2 items from index 3, means 4 and 5
+
+console.log(b); // => [ 1, 2, 3, 6 ]
+```
+
+##### .isort(compareFunction)
+
+Return a new array sorted by *compareFunction*.
+
+This method does the same thing as [Array.sort](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort), but immutable.
+
+```
+let users = stabilize([
+  {
+    name: "Bob",
+    age: 28
+  },
+  {
+    name: "Anne",
+    age: 21
+  },
+  {
+    name: "Jim",
+    age: 33
+  },
+    {
+    name: "Kate",
+    age: 17
+  }
+]);
+let sortedUsers = users.isort((a, b) => {
+  let ag = a.age;
+  let bg = b.age;
+  if (ag === bg) {
+    return 0;
+  }
+  return ag < bg ? -1 : 1;
+});
+
+console.log(sortedUsers);
+```
+
+Output:
+
+```
+[ { name: 'Kate', age: 17 },
+  { name: 'Anne', age: 21 },
+  { name: 'Bob', age: 28 },
+  { name: 'Jim', age: 33 } ]
+```
+
+
+##### .ireverse()
+
+This method does the same thing as [Array.reverse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reverse), but immutable.
+
+For example now you can reverse the above *sortedUsers* array:
+
+```
+let reversedUsers = sortedUsers.ireverse();
+console.log(reversedUsers);
+```
+
+Output:
+
+```
+[ { name: 'Jim', age: 33 },
+  { name: 'Bob', age: 28 },
+  { name: 'Anne', age: 21 },
+  { name: 'Kate', age: 17 } ]
+```
+
+##### .shuffle()
+
+Return a clone of given array with shuffled elements.
+
+```
+let shuffledUsers = sortedUsers.shuffled();
+console.log(shuffledUsers);
+```
+
