## What it is
ExDoc is a documentation generation tool for Elixir and Erlang projects that produces HTML, Markdown (including llms.txt), and EPUB output from API documentation. It is the tool behind HexDocs and Elixir's official documentation, with features like full-text search, version dropdowns, and source links.

## Use cases
- generate html documentation for an elixir project
- publish api docs to hexdocs
- produce epub offline documentation
- generate llms.txt markdown docs for a library
- add full-text search to project documentation
- document an erlang project with rebar3
- create guides and cheatsheets alongside api docs

## When to choose
- you maintain an Elixir or Erlang library or application and want standard HexDocs-style documentation
- you need offline-accessible HTML or EPUB docs generated from docstrings
- you want hosted docs with search, versioning, and source links out of the box

## When to avoid
- your project is not in the Elixir/Erlang ecosystem
- you need a different documentation format like PDF or man pages
- you want a general-purpose static site generator rather than API doc generation

## Facets
- artifact type: library
- maturity: active
- function: documentation, markdown, search-engine, cli
- domain: documentation, developer-tools, programming-languages
- platform: elixir, cross-platform
- tags: doc-generator, html, epub, hexdocs, elixir, erlang, api-docs
