Licencing for Astro themes

[lament inlet]

Hi everynone.

I would like to use one of these themes https://astro.build/themes/blog/ for my website. On a number of them it says "Free", for example on the "Sleek" one, that looks like this https://blogster-sleek.netlify.app/.

My question is, if I adapt and change these themes for my website, do I

1 ) need to get some kind of licence from the creator, respectively credit him on my website? (It seems that at least the Astro code runs under the MIT licence, see https://github.com/flexdinesh/blogster, but I wasn't able to find the licence out for this specific Astro theme)
2) Do I need to keep the "This blog is built with Blogster" text on the bottom of the page?

I would like my website to be minimalistic and therefore if I would need to include any credits to other creators etc., I'd rather choose a different theme or roll my own.

https://github.com/flexdinesh/blogster do have a LICENSE file in github, it's MIT.
It does not matter where you get the link from, from Astro or from internet, what matters is the final codebase you endup using and the license of each single dependency and repo.
I really hope each Theme do have a license, otherwise it needs to be reported as the fallback process of contacting the author and getting an authorization is not proctical if a license is missing.
Also, leaving logos and links must all be mentioned in the license, if just MIT then just MIT, that's how I contributed my theme too https://astro.build/themes/details/astro-big-doc/
Pay attention on licenses of dependencies though with regard to mentions. Usually incompatible licenses should not be combined, but you never know.

Thanks for answering.
Hm.... so that mean I need to keep the "This blog is built with Blogster" text on the bottom of the page, or can I delete it?

You can delete it
