 # Data Structures & Algorithms
 
-This repository contains implementation of some fundamental data structures and algorithms in Computer Science. It is
-primarily used as a teaching resource and is currently being developed by ex-2040s students.
+This repository contains implementation and discussion notes (intuition, applications, analysis) 
+of some fundamental data structures and algorithms in Computer Science. <br>
+It is aligned with [CS2040s](https://nusmods.com/courses/CS2040S/data-structures-and-algorithms) syllabus taught at NUS.
 
-The project uses Gradle and the structure is optimised for IntelliJ IDEA since implementation are mostly written in
-Java.
+The work here is continually being developed by CS2040s Teaching Assistants(TAs) and ex-2040s students. 
+Lecture content has been covered and future plans include deeper discussion into the tougher parts of tutorials.
 
-**Note**: This is still being developed. Those below with links mean that they are complete (alongside testing). We
-project to complete CS2040s course content by November and along the way, add interesting algorithms/problems. We are
-hopeful that the subsequent batches of students (from AY23/24 S2) will benefit greatly from this.
+The project's structure is optimised for IntelliJ IDEA as per the course's preferred IDE. 
+Gradle is used for development.
