# *minimal-emacs.d* - A Customizable Emacs `init.el` and `early-init.el` that Provides Better Defaults and Faster Startup

The **minimal-emacs.d** project is a lightweight, bloat-free Emacs base (`init.el` and `early-init.el`) that **gives you full control over your configuration** (without the complexity of, for instance, Doom Emacs or Spacemacs). It provides better defaults, an optimized startup, and a clean foundation for building your own vanilla Emacs setup.
