Most of the work for this application was created by myself, an indie game developer. However, certain aspects of the work for this app were helped by resources found online and I wanted to attribute them here.
The Art for the chess pieces was found at the following website: https://commons.wikimedia.org/wiki/Template:SVG_chess_pieces
The icon for my app was created with the use of Openart AI which can be found at: https://openart.ai/home
The google feature page was created with the use of hotpot AI which can be found at: https://hotpot.ai/
The YouTube series by Sebastian Lague named Coding Adventure: Chess was instrumental in helping me work towards a better chess engine: https://www.youtube.com/watch?v=U4ogK0MIzqk&t=260s
The Coding Adventure github link is: https://github.com/SebLague/Chess-Coding-Adventure
The chess programming wiki was also helpful in my creation of this application: https://www.chessprogramming.org/Main_Page
Lichess has some resources available to the public in a github page as well and it was helpful: https://github.com/lichess-org/lila
