You can create mods for Picotron Solitaire Suite from this example project cart. the cart contains a single solitaire variant from which you can learn how the api works and build your own games from. Try to keep all changes you make inside cart_games/ and card_backs/. Though you should probably adjust suite_scripts/main_menu.lua to better match your game.
I highly recommennd reading the READMEFIRST file inside the cart.
All the functions inside cards_api/ and suite_scripts/ should have comments that help tell you what they do. The readme files in for the suite and api git repositories also have some information on the available functions. You can also look at the games inside the suite in order to get an idea of how those games apply the api and suite functions.

If you make any mods, you can post them on the BBS so other people can play them on their own or download them through the mod manager on the main suite cart. But make sure you add the tag solitaire-suite-mod and add this cart as a fork, which can be found by clicking the edit button below your cart on the bbs or be done by submitting the cart through (https://www.lexaloffle.com/picotron.php?page=submit&respond_to=pss_example_project). These are important to help people search for mod carts and for future functionality for a mod explorer.
