Reference Files

Task	File
Config file, CLI, entry points	config.md
Format, target, dts, exports, validation	output.md
Shims, unbundle, watch, frameworks, WASM	features.md
Plugins, hooks, lint, programmatic, migration	advanced.md

Loading Files

Consider loading these reference files based on your task:

references/config.md - if setting up tsdown.config.ts, CLI, or entry points
references/output.md - if configuring output format, target, .d.ts, exports, or validation
references/features.md - if using shims, unbundle, watch mode, framework integrations, or WebAssembly
references/advanced.md - if writing plugins, using linting/validation, programmatic API, or migrating from tsup

DO NOT load all files at once. Load only what's relevant to your current task.
