-# Buffer-4.0
-Buffer is a Data Structures and Algorithms Project series, in which students can participate as mentees in teams of 3-4 people. 
-This year the themes on which students can create a project are-
+ALPHA CLANS: MISSION TO SERVE HUMANITY!
 
-1. Healthcare
-2. Digital Society
-3. Open Innovation
-4. Custom data structure to store data
+TEAM MEMBERS (SY): 
+   - NIKITA PAWAR
+   - SAKSHI WAGH
+   - AARYA AMBEKAR
+   - PURVA SARDA
 
-This repository is created for all the teams to be able to upload their final project source code for the same. 
+PROBLEM STATEMENT:
+Building a console-based programme to make donations anywhere anytime in a click.
 
-While submitting, note that: 
+FEATURES:
+This is a console-based programme which simulates Disaster Campaign Funding.
+It enables the admin to securely login into the admin’s window to add and edit campaign details.
+It allows users to create their accounts on the platform to make donations to various campaigns.
+Users can choose how much to donate and which campaign to donate to.
+Appropriate output is generated according to the user’s and admin's input.
 
-Each folder should have the name of the team and inside a readme file with team member details, (name, year, branch) and their theme. The readme file should also contain the link to their presentation as well as the drive link where both the report documents would be stored. 
+DATA STRUCTURES USED:
+1. SINGLY LINKED LIST:
+  List of all users
+  List of donations they make.
+  List of user's details.
+Size of these lists is dynamic, hence singly linked list is used for efficient insertion and deletion.
 
-Happy Coding :)
+2. ARRAY OF OBJECTS : 
+  To store the requirements of the each campaign.
+Array of object allows us to deal with number of attributes connected with a single entity.
+
+3. ARRAY: 
+  Used to implement array of objects.
+
+LEARNINGS AND OUTCOMES:
+Importance and application of Abstract Data Types (ADTs) and Flowcharts
+Application and implementation of various linear data structures
+Importance of static keyword (used a static variable to keep track object we are refering to)
+Learned a powerful tool - GitHub
+
+WHAT'S NEXT:
+User interface for better user experience.
+Database for storing user history and donation data.
