What do you want to do? My best advice would be to search up some dot files from people you may follow on GitHub. There are all kinds of configs, but typically just fork someone’s you like then make minor tweaks. Here’s mine, I also linked the three people I copied from in my read me:
Is that a thing anyone does? Follow people on github? I'm vaguely aware that they tried making github social media but I never heard of anyone actually using it like that.
I don’t really follow people for the social media. If there are devs I like I get to easily see what projects they follow, fork, or contribute to. It a good way to see what’s out there IMO, project wise. I found many awesome libs and CLTs this way.
You can either use lunarvim or nvchad to get started quickly. It's easier to override default bindings, plugin config etc. in nvchad. Or you can use their configuration as reference and pick and choose what you need.
