## What it is
MELPA is the largest community package archive for Emacs, built automatically from upstream source repositories using recipe files. This repository contains the package recipes and the build machinery that compiles and publishes packages to melpa.org.

## Use cases
- install emacs packages from melpa
- add a new emacs package to melpa
- write a melpa recipe for my elisp package
- build emacs lisp packages automatically from git
- find emacs packages to install
- set up package.el to use melpa archive

## When to choose
- you maintain an Emacs Lisp package and want it distributed via MELPA
- you want to understand or mirror how MELPA builds packages
- you need to submit or fix a package recipe

## When to avoid
- you just want to install packages - use the melpa.org archive directly in Emacs, not this repo
- you need a package manager for non-Emacs ecosystems

## Facets
- artifact type: service
- maturity: active
- function: package-manager, build-tool, developer-tools
- domain: developer-tools, text-editors
- platform: windows, cli
- tags: emacs-lisp, package-archive, melpa, package-recipes, elisp, automation, emacs, linux, macos
