## What it is
GNU Emacs is the extensible, customizable, self-documenting real-time display text editor built around an Emacs Lisp interpreter. It supports content-aware editing modes, full Unicode, a package system, and a wide range of functionality beyond text editing such as email, IRC, and project management.

## Use cases
- edit source code with syntax highlighting
- customize my editor with lisp
- manage email and irc from my editor
- extend a text editor with packages
- write and evaluate elisp interactively
- use one editor across linux mac and windows

## When to choose
- you want a deeply extensible, scriptable editor with a huge package ecosystem
- you prefer keyboard-driven, self-documenting tooling that can host email, org-mode, and development workflows
- you want a free software editor maintained by the GNU project across many platforms

## When to avoid
- you want a lightweight editor with minimal configuration
- you prefer mouse-centric GUI editors with out-of-the-box defaults
- you are unwilling to learn Emacs Lisp or keybindings
