## What it is
The LaTeX2e kernel is the core source code of the LaTeX document preparation system, maintained by the LaTeX Project. It provides the base format, essential tools, graphics, and math support that underpin LaTeX typesetting, distributed to users via CTAN and TeX distributions like TeXLive, MacTeX, and MiKTeX.

## Use cases
- typesetting scientific papers with complex math
- producing technical documentation and books
- generating journal articles with automatic bibliographies
- creating slide presentations with LaTeX
- contributing fixes to the LaTeX kernel
- writing multilingual documents with cross-references

## When to choose
- you need to fix or develop the LaTeX kernel itself
- you want to track or report bugs in core LaTeX components
- you need the unpackaged sources to build a custom LaTeX format

## When to avoid
- you just want to install and use LaTeX - get TeXLive, MacTeX, or MiKTeX instead
- you need help using LaTeX - use community support sites
- your issue involves third-party packages not maintained by the LaTeX team

## Facets
- artifact type: library
- maturity: active
- function: templating, documentation, pdf
- domain: documentation, developer-tools, education
- platform: cross-platform, cli
