## What it is
A guide documenting how to use Nix for Haskell development in production, covering two workflows: Nix-provisioned development environments with cabal, and Nix-driven builds for CI. It includes example Nix derivations and best practices for scaling Haskell projects across teams.

## Use cases
- set up a Nix-based Haskell development environment
- build Haskell projects with Nix for continuous integration
- learn how Nix complements cabal instead of replacing it
- manage multiple private Haskell projects across a team with Nix
- migrate from stack to Nix for Haskell dependency management
- configure release.nix files for Haskell projects

## When to choose
- you use Haskell with Nix and want production-tested guidance
- you need reproducible Haskell builds for CI like Hydra
- you want to understand Nix vs stack tradeoffs for Haskell

## When to avoid
- you want a step-by-step tutorial for Nix itself rather than Haskell integration
- you need maintained tooling or a library rather than documentation
- your project is small and stack.yaml simplicity suffices

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: build-tool, developer-tools, documentation
- domain: developer-tools, programming-languages
- platform: cli
- tags: nix, haskell, cabal, guide, tutorial, devops, linux, macos
