How to setup Neovim from Scratch - Complete Guide (Including TMUX, Lazy and LSP)

My NeoVim config needed an update, so, I decided to configure it from scratch! I've documented each step for an awesome neovim setup, including installing the Lazy Nvim plugin manager, integrating TMUX, setting up our Language Servers with Lspconfig and much more.

In light of the recent archiving of null-ls, we will also explore switching to efm-langserver, a performance-optimized alternative for linting and formatting with broad language support. We will set up the LSPs, linters and formatters for Python, Lua and Typescript. Plus, we'll delve into transitioning to Lazy Nvim for a more streamlined plugin management experience.

This video tutorial is designed for both beginners as well as those already using NeoVim and looking to optimise their NeoVim configuration (see timestamps to skip ahead where needed!).
