 This template should help get you started developing with Svelte in Vite.
 
-## Running the app
-
-```bash
-npm install
-npm run dev
-```
-
-## Running tests
-
-- **Watch mode** (re-runs on file changes):  
-  `npm run test`
-
-- **Single run** (CI-friendly):  
-  `npm run test:run`
-
-- **Coverage report**:  
-  `npm run test:coverage`
-
-Tests use Vitest and `@testing-library/svelte`. Place test files next to the code they cover (e.g. `Component.test.js` beside `Component.svelte`) or in a `__tests__` directory.
-
 ## Recommended IDE Setup
 
 [VS Code](https://code.visualstudio.com/) + [Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode).
