I'm currently building a website for a small, local soccer club. I'm building it, based on a template of html5up.net/. As far as I know, their only requirement for doing so is that I give them credit. I do that, at the bottom of every page.
However, I was wondering which license I should add to this website, to be safe? I was thinking about GPL? If I remember correctly, it allows others to use my code, so long as their products are open source and use the same license. Do I need to mention this license somewhere specific on the site, or is a README file on GitHub sufficient? If possible, I'd rather not clutter the site with it.
Also, what do I do with the copyrights disclaimer? On default, the template of Html5up says:
© Untitled. All rights reserved
Do I replace Untitled by my own name? Or the one of the soccer club? I would like my own name to be credited, to be perfectly honest.
