Hi @maDazza ! Thanks for showing interest. You can directly use examples and also can download them directly from the web editor.
If you want to do it manually, you can find the .js file in p5.teach/dist directory. The latest version (unstable features) is GObject branch. Follow setting up instructions to build the library if you want to customize the library. If any problem arises in setting up or finding any bug please report it in the issue tab or message me.
