How to modify and run the extension

[OoDeLally]

Hello,

I'm trying to improve the extension.
I cloned the repo, and run it on developer mode in Chrome.

I have the following error: lib/common/js/jquery-3.3.1.min.js not found. It is not included in the folder.
So I manually added it (is it the right thing to do?)

Then I finally can run it. But the menu has no css style. The repo doesnt include src/editCardModel.css.

Finally I am not sure what I should modify. The src folder is almost empty, and the JS files at the root look like big generated files. I believe you have somewhere some actual source files, and it would be great if we can use them to improve the extension.

Thanks!
