-A `Set` where an order of elements matters or an `OrderedCollection` with no duplicates. Supports the complete API of `Set` and `OrderedCollection`.
+A `CTOrderedSet` is a collection that combines the properties of a `Set` and an `OrderedCollection`. It maintains the order of elements while ensuring that there are no duplicates, similar to a `Set`. This makes it a useful data structure when you need to keep track of the order in which items were added, while also enforcing uniqueness.
+
+### Key Features
+- **Maintains Insertion Order**: Elements are stored in the order they were added.
+- **Ensures Uniqueness**: No duplicate elements are allowed.
+- **Indexed Access**: Elements can be accessed by their index, similar to an array.
+- **Rich API**: Combines methods from both `Set` and `OrderedCollection`, allowing for flexible usage.
+- **Developer Productivity**: Simplifies code by eliminating the need for manual duplicate checks and order management.
 
 ## Installation
-To install `CTOrderedSet`, go to the Playground (`Ctrl+OW`) in your [Pharo](https://pharo.org/) image and execute the following Metacello script (select it and press Do-it button or `Ctrl+D`):

 ## How to use it?
+You can create an `OrderedSet` and use it like this:
+```smalltalk
+| orderedSet |
+orderedSet := CTOrderedSet new.
+orderedSet add: 'Apple'.
+orderedSet add: 'Banana'.
+orderedSet add: 'Apple'.  "This will not add a duplicate"
+orderedSet add: 'Cherry'.
+orderedSet do: [ :each | Transcript show: each; cr ].
+```
+This will output:
+```
+Apple
+Banana
+Cherry
+```
 
-`CTOrderedSet` has the same API as `OrderedCollection`, extended with the methods of `Set`. So instance creation looks the same:
+### Real World Use Case: Blog Tag Management
+Let's explore a comprehensive example that demonstrates the power of `OrderedSet` in a real-world scenario - managing tags for a blog post. This example illustrates how to maintain order, ensure uniqueness, and perform efficient operations on tags.
 
-```Smalltalk
-firstBasket := CTOrderedSet withAll: #(apple apple orange banana orange banana).
-secondBasket := CTOrderedSet withAll: #(banana apple banana banana). 
-```
+```smalltalk
+"Blog post tag management - Maintain order, Ensure uniqueness"
 
-Or you can use the `asOrderedSet` method:
+"Traditional approach with OrderedCollection - problematic"
+blogTags := OrderedCollection new.
+blogTags 
+    add: 'Programming'; 
+    add: 'Pharo'; 
+    add: 'Tutorial'; 
+    add: 'Programming';  "Oops! Duplicate"
+    add: 'Beginner';
+    add: 'Pharo'.        "Another duplicate"
+"Manual cleanup required - inefficient and error-prone"
+blogTags := blogTags asSet asOrderedCollection.  "Loses order!"
+"Result: Unpredictable order, Manual management needed"
 
-```Smalltalk
-firstBasket := #(apple apple orange banana orange banana) asOrderedSet.
-secondBasket := #(banana apple banana banana) asOrderedSet. 
+"OrderedSet approach - Elegant and Automatic"
+blogTags := CTOrderedSet new.
+blogTags 
+    add: 'Programming'; 
+    add: 'Pharo'; 
+    add: 'Tutorial'; 
+    add: 'Programming';  "Automatically ignored - No duplicate"
+    add: 'Beginner';
+    add: 'Pharo'.        "Automatically ignored - No duplicate"
+
+"Result: #('Programming' 'Pharo' 'Tutorial' 'Beginner') - Perfect order, No duplicates"
+
+"Adding tags from user input or external sources"
+userInputTags := #('Advanced' 'Programming' 'Smalltalk' 'Tutorial').
+blogTags addAll: userInputTags.
+"Result: #('Programming' 'Pharo' 'Tutorial' 'Beginner' 'Advanced' 'Smalltalk') - Maintains order, no duplicates"
+"Notice: Duplicates automatically filtered, new tags appended in order"
+
+blogTags includes: 'Pharo'. "Returns: True"
+blogTags includes: 'JavaScript'. "Returns: False"
+
+firstTag := blogTags first. "Access first tag - 'Programming'"
+lastTag := blogTags last.   "Access last tag - 'Smalltalk'" 
+thirdTag := blogTags at: 3. "Access third tag - 'Tutorial'"
 ```
