 ## :file_folder: Structure of the repository
 
-As of now, the repository contains a file called [`useful_links.md`](useful_links.md) and 2 main directories: **Data Structures** and **Algorithms**.
+As of now, the repository contains 3 main directories: **[Data Structures](data_structures)**, **[Algorithms](algorithms)** and **[Bookmarks](bookmarks)**.
 
 ### Data Structures
 
 Contains all data structure questions categorised into sub-directories like stack, queue, etc according to their type.
 
-1. Array
-2. Dictionary
-3. Binary Search Tree
-4. Linked List
-5. Stack
-6. Graphs
-7. Circular Linked List
+1. [Array](data_structures/array)
+2. [Dictionary]()
