you can manually install the colorscheme by downloading this repo and moving `detail.vim` to where your plugins are installed. if you use a plugin manager and it needs you to add a manually installed plugin to your config so that it doesn't get arbitrarily deleted, you should do that.
(you do not have to use vim to edit `details` files. in fact, i would recommend that you _not_ do that if you've never coded before; it's merely where i prefer to write so i'm providing tooling for it. something like textedit or notepad might serve you better.)
