 I've always been fascinated with vim and had been functioning with other's customized vim configs. Felt like working with a crutch. Decided to take things in my own hands and try to learn the "modern" vim ecosystem and start with nvim. Tried NvChad but the native lsp just didn't sit right with me, and also felt like I'm diving down the same path of using somebody else's customized setups. And so this repo was born.
