 ## Overview
 
-A tool for visualizing numerous pathfinding algorithms. Current implementation of the project involves four search-based planning algorithms: BFS, DFS, DIJKSTRA and A-Star. The project extensively uses SFML and Modern C++ features such as smart pointers, lamda expressions along with multi-threading concepts.
