I've just started my journey with web development so please forgive me for being noisy on your forum these days.
I'd like to apply some custom styling to Adam theme which I can't implement with editing on site.
I have no idea how to use Composer and Gulp so I'd like to make changes "the old way" by hands and editor.
Help me please with my three noob questions:
1) After theme folder cloning should I use default *.less files for that purpose or just change values in adam.min.css?
2) So because of no Gulp and no Composer should I delete gulpfile.js, composer.json, package-lock.json and package.json?
3) After all changes how to make this cloned theme safe from future updates of default packages?
Can you please guide me?
