-# sv
+# My SvelteKit App
 
-Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+A SvelteKit application with TypeScript support, configured with all standard file types.
 
-## Creating a project
+## Development Commands
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```sh
-# create a new project
-npx sv create my-app
-```
-
-To recreate this project with the same configuration:
-
-```sh
-# recreate this project
-bun x sv create --template minimal --types ts --install bun my-sveltekit-app
-```
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
 
 ```sh
+# Start development server
 npm run dev
 
-# or start the server and open the app in a new browser tab
+# Start with browser open
 npm run dev -- --open
+
+# Type checking
+npm run check
+
+# Type checking with watch mode
+npm run check:watch
+
+# Build for production
+npm run build
+
+# Preview production build
+npm run preview
+
+# Sync SvelteKit
+npm run prepare
 ```

+## SvelteKit File Types
+
+### Page Files
+- `+page.svelte` - Component for a route page, renders HTML and handles UI
+- `+page.ts` - Universal load function that runs on server and client
+- `+page.server.ts` - Server-only load function with access to cookies, database, and server APIs
+
+### Layout Files
+- `+layout.svelte` - Wraps child routes with shared UI (navbar, footer, etc.)
+- `+layout.ts` - Universal load function that provides data to all child routes
+- `+layout.server.ts` - Server-only layout load for shared data (auth session, user info, etc.)
+
+### Special Files
+- `+error.svelte` - Custom error page component, renders when `error()` is thrown
+- `+loading.svelte` - Loading indicator shown during navigation
+- `+not-found.svelte` - Custom 404 page when a route doesn't exist
+
+### Server Endpoints
+- `+server.ts` - API endpoint (GET, POST, PUT, DELETE, etc.) for RESTful routes
+
+### Root Files
+- `src/app.html` - HTML template for the entire application
+- `src/app.d.ts` - TypeScript declarations extending SvelteKit's global types
+- `src/hooks.server.ts` - Server-side hooks for auth, cookies, middleware
+- `src/hooks.client.ts` - Client-side hooks for browser-specific initialization
+
+## Getting Started
