 ### Prerequisites
 
-- Node.js v20+ (current project uses v20.19.5)
-- npm v10+ (current project uses v10.8.2)
+- Bun (use bun, bunx with --bun instead of node or npm)
 
 ### Bootstrap and Build
 
-- Install dependencies: `npm install` -- takes 5 seconds
-- Format code: `npm run format` -- fixes all prettier formatting issues
-- Build the application: `npm run build` -- takes 10 seconds from clean state. NEVER CANCEL.
-- Run type checking: `npm run check` -- validates TypeScript and Svelte components (currently fails due to QPDF WASM types)

 ### Development Workflow
 
-- Start development server: `npm run dev` -- serves on http://localhost:5173/
-- Start production preview: `npm run preview` -- serves built app on http://localhost:4173/
+- Start development server: `bun run dev` -- serves on http://localhost:5173/
+- Start production preview: `bun run build && bun run preview` -- serves built app on http://localhost:4173/
 - The dev server supports hot reload and the app initializes QPDF WASM module successfully
 
 ### Linting and Code Quality
 
-- Format code: `npm run format` -- uses Prettier to format all files
-- **IMPORTANT**: `npm run lint` currently fails due to ESLint circular dependency issue in the configuration. This is a known issue that does not affect the build process.
-- Always run `npm run format` before committing changes
-- Use prettier for code formatting, not ESLint for this project

 ## Application Architecture

 - QPDF WASM integration: Client-side PDF processing and encryption
 - Progressive Web App features: Service worker, offline support, installability
 
-## Validation and Testing
-
-### Manual Testing Scenarios
-
-After making changes, ALWAYS test these scenarios:
-
-1. **Basic file encryption**:
-    - Start dev server: `npm run dev`
-    - Navigate to http://localhost:5173/
-    - Verify the "Choose File" button appears
-    - Enter a user password
-    - Confirm encryption button becomes enabled
-
-2. **Advanced permissions**:
-    - Toggle "Advanced Permissions" checkbox
-    - Verify owner password field appears
-    - Test all permission checkboxes and the printing dropdown
-    - Confirm owner password requirement message appears
-
-3. **Navigation**:
-    - Test navigation to /install page
-    - Test navigation to /privacy page
-    - Verify all navigation links work
-
-4. **Production build**:
-    - Build application: `npm run build`
-    - Start preview: `npm run preview`
-    - Test on http://localhost:4173/
-    - Verify application works identically to dev mode
-
-### Build Validation
-
-- Clean build from scratch: `rm -rf build .svelte-kit && npm run build`
-- Build output size: Client bundle ~2.5MB (includes 1.3MB QPDF WASM file)
-- Build warnings about large chunks are expected due to QPDF WASM
-- PWA service worker and workbox files are generated automatically

-## Common Tasks and Commands
-
-### Development Commands
-
-```bash
-# Start fresh development
-npm install && npm run dev
-
-# Clean rebuild
-rm -rf build .svelte-kit && npm run build
-
-# Format and prepare for commit
-npm run format
-
-# Full development workflow
-npm install && npm run format && npm run build && npm run dev

-- `src/routes/+page.svelte`: Main application logic and UI
-- `vite.config.ts`: Build configuration and PWA settings
-- `svelte.config.js`: SvelteKit configuration
-- `package.json`: Dependencies and scripts

-- Service worker files: `sw.js` and `workbox-*.js`
-
-## Known Issues and Limitations
-
-### ESLint Configuration
-
-- `npm run lint` fails with circular dependency error in ESLint configuration
-- This does not affect the build process or application functionality
-- Use `npm run format` for code formatting instead
-- The issue is related to ESLint v9 compatibility with the current plugin configuration
-
-### TypeScript Checking
-
-- `npm run check` shows one error related to QPDF WASM module types
-- This is a known limitation with the @neslinesli93/qpdf-wasm package types
-- The error does not prevent the application from working correctly
-
 ### Build Warnings
 
 - Large chunk size warnings are expected due to the QPDF WASM file (1.3MB)

-## Performance Expectations
-
-- `npm install`: 5 seconds
-- `npm run build`: 10 seconds from clean state
-- `npm run format`: Near-instant
-- Development server startup: 1-2 seconds
-- QPDF WASM module initialization: < 1 second in browser
