Choose a starting point, save its downloadable Pkl file as hk.pkl, and adapt the tools and paths to your project. Each page includes the exact file it offers for download.

Example	Tools and concepts
JavaScript and TypeScript	ESLint, Prettier, and optional TypeScript checking
Python	Ruff linting and formatting, plus optional mypy
Monorepo	Component groups, inherited defaults, and multiple toolchains
Custom steps	Check/fix commands and self-contained step tests

Install any external tools the example invokes. Then validate and inspect the configuration before installing hooks:

hk validate
hk check --all --plan
hk install

For package environments and editor-launched hooks, see mise integration. For individual properties, see configuration.
