+## Usage
+
+Those templates dependencies are maintained via [pnpm](https://pnpm.io) via
+`pnpm up -Lri`.
+
+This is the reason you see a `pnpm-lock.yaml`. That being said, any package
+manager will work. This file can be safely be removed once you clone a template.
+
+```bash
+$ npm install # or pnpm install or yarn install
+```
