+# Common Issues and Solutions
+
+## ESC Key Closes the Game
+
+### Problem
+By default, RayLib sets ESC as the exit key. When you press ESC, `WindowShouldClose()` returns true and the game closes immediately, even if you want to use ESC for pause menus or other game functionality.
+
+### Solution
+Disable the default ESC exit key behavior by calling `RL.SetExitKey(0)` in your `RL.init()` function:
+
+```lua
+function RL.init()
+  -- Window setup
+  RL.SetWindowTitle("My Game")
+  
+  -- Disable ESC key from closing the window
+  RL.SetExitKey(0)  -- 0 = KEY_NULL (no exit key)
+  
+  -- OR set a different exit key
+  -- RL.SetExitKey(RL.KEY_F12)  -- Use F12 instead
+  
+  -- Rest of initialization...
+end
+```
+
+### Options
+
+**Option 1: No Exit Key (Recommended for Games)**
+```lua
+RL.SetExitKey(0)  -- Disable exit key completely
+```
+Now ESC (and any key) won't close the game. Handle exit through:
+- Menu option (File → Exit)
+- Alt+F4 (Windows default)
+- Close window button (X)
+
+**Option 2: Different Exit Key**
+```lua
+RL.SetExitKey(RL.KEY_F12)  -- Use F12 to exit
+```
+Now only F12 will close the game, ESC is free for pause menus.
+
+**Option 3: Custom Exit Handling**
+```lua
+-- In RL.update()
+if RL.IsKeyPressed(RL.KEY_ESCAPE) then
+  -- Show pause menu or confirmation dialog
+  GameState.push(pauseMenu)
+end
+
+if RL.IsKeyPressed(RL.KEY_F10) then
+  -- Exit game
+  RL.CloseWindow()
+end
+```
+
+### Technical Details
+
+**What happens by default:**
+1. RayLib sets ESC as the default exit key
+2. When ESC is pressed, `WindowShouldClose()` returns true
+3. Main loop in `src/main.c` checks this and exits
+
+**After calling `RL.SetExitKey(0)`:**
+1. No key triggers `WindowShouldClose()`
+2. ESC is now available for your game logic
+3. You control when the game exits
+
+### Example: Pause Menu with ESC
+
+```lua
+-- In your game state:
+function GameState:update(dt)
+  -- Pause with ESC
+  if RL.IsKeyPressed(RL.KEY_ESCAPE) then
+    if self.paused then
+      self.paused = false
+    else
+      self.paused = true
+    end
+  end
+  
+  if not self.paused then
+    -- Update game logic
+  end
+end
+```
+
+### Template Fix
+
+The template's `main.lua` has been updated with:
+```lua
+RL.SetExitKey(0)  -- Disable ESC exit key
+```
+
+This allows the game state to use ESC for pause functionality without closing the game.
+
+### Related Functions
+
+- `RL.SetExitKey(key)` - Set which key exits the game
+- `RL.WindowShouldClose()` - Check if game should close
+- `RL.CloseWindow()` - Manually close the window
+- `RL.IsKeyPressed(key)` - Check if key was pressed this frame
+
+### Development Tip
+
+During development, you might want quick exit. Consider:
+```lua
+function RL.init()
+  RL.SetExitKey(0)  -- Disable ESC
+  
+  -- But add debug exit key
+  if DEBUG_MODE then
+    RL.SetExitKey(RL.KEY_F12)
+  end
+end
+```
+
+Or handle it in update:
+```lua
+function RL.update(dt)
+  -- Debug: Quick exit with Shift+ESC
+  if RL.IsKeyDown(RL.KEY_LEFT_SHIFT) and RL.IsKeyPressed(RL.KEY_ESCAPE) then
+    RL.CloseWindow()
+  end
+end
+```
+
+## Other Common Issues
+
+### Window Closes When X Button Clicked
+This is normal behavior. If you want to show a confirmation dialog:
+```lua
+function RL.update(dt)
+  if RL.WindowShouldClose() then
+    -- Show "Are you sure?" dialog
+    -- If player cancels, need to prevent close somehow
+  end
+end
+```
+Note: Preventing X button close is tricky with RayLib's current API.
+
+### Alt+F4 Closes Game
+This is OS-level behavior and cannot be easily disabled. It's recommended to save game state frequently.

+
+## 📚 Libraries Included
+
+### Classic (OOP)
+Object-oriented class system by rxi.
+
+```lua
+local Object = require("lib.classic")
+local Player = Object:extend()
+
+function Player:new(x, y)
+  self.x = x
+  self.y = y
+end
+
+function Player:update(dt)
+  -- Update logic
+end
+
+local player = Player(100, 100)
+```
+
+### GameState
+State management system inspired by hump.gamestate.
+
+```lua
+local GameState = require("lib.gamestate")
+local menu = require("states.menu")
+
+-- Register callbacks
+GameState.registerEvents()
+
+-- Switch state
+GameState.switch(menu)
+
+-- Push state (with return)
+GameState.push(pauseMenu)
+GameState.pop()  -- Returns to previous state
+```
+
+**State Callbacks:**
+- `state:enter(previous, ...)` - Entering state
+- `state:leave()` - Leaving state
+- `state:resume(previous, ...)` - Returning via pop()
+- `state:update(dt)` - Frame update
+- `state:draw()` - Rendering
+- `state:event(event)` - Input events
+
+### Animation
+Sprite sheet animation system.
+
+```lua
+local Animation = require("lib.animation")
+
+-- Load texture
+local playerTexture = RL.LoadTexture("assets/player.png")
+
+-- Create animation (32x32 frame size)
+local anim = Animation.new(playerTexture, 32, 32, {
+  idle = {frames = {1, 2, 3, 4}, fps = 8, loop = true},
+  walk = {frames = {5, 6, 7, 8, 9, 10}, fps = 12, loop = true},
+  jump = {frames = {11, 12, 13}, fps = 10, loop = false}
+})
+
+-- Play animation
+anim:play("idle")
+
+-- In update loop
+anim:update(dt)
+
+-- In draw loop
+anim:draw(x, y)
+
+-- Or simple draw (no rotation/scale)
+anim:drawSimple(x, y)
+
+-- Advanced features
+anim:setFlip(true, false)  -- Flip horizontally
+anim:setScale(2, 2)        -- Scale 2x
+anim:setTint(RL.RED)       -- Color tint
+anim:pause()               -- Pause animation
+anim:resume()              -- Resume
+anim:stop()                -- Stop and reset
+```
+
+## 🎮 Example States
+
+### Menu State (states/menu.lua)
+- Keyboard navigation (Up/Down)
+- Start game / Options / Exit
+- Clean UI rendering
+
+### Game State (states/game.lua)
+- Player movement (WASD/Arrows)
+- Pause menu (ESC/P)
+- Animation integration example
+- Basic game loop
+
+## 🎨 Adding Assets
+
+### Sprite Sheets
+Place sprite sheets in `assets/` folder:
+
+```
+assets/
+├── player.png      # Player sprite sheet (grid-based)
+├── enemy.png       # Enemy sprites
+├── explosion.png   # Explosion animation
+└── background.png  # Background image
+```
+
+**Sprite Sheet Format:**
+- Grid-based (equal-sized frames)
+- Frames read left-to-right, top-to-bottom
+- Example: 32x32 frames in 256x256 texture = 8x8 grid (64 frames)
+
+### Sounds & Music
+```lua
+-- In state:enter()
+self.music = RL.LoadMusicStream("assets/music.ogg")
+self.jumpSound = RL.LoadSound("assets/jump.wav")
+
+-- In state:update()
+RL.UpdateMusicStream(self.music)
+
+-- Play sound
+RL.PlaySound(self.jumpSound)
+```
+
+## 🔧 Configuration
+
+### Window Settings (main.lua)
+```lua
+local GAME_TITLE = "My Awesome Game"
+local WINDOW_WIDTH = 1280
+local WINDOW_HEIGHT = 720
+local TARGET_FPS = 60
+local START_FULLSCREEN = false  -- Start in fullscreen?
+```
+
+For complete window configuration (fullscreen, resizable, etc.), see [WINDOW_CONFIG.md](WINDOW_CONFIG.md).
+
+### Exit Key Behavior
+By default, the template disables ESC as an exit key so you can use it for pause menus:
+```lua
+RL.SetExitKey(0)  -- 0 = No exit key
+```
+
+To change this behavior, see [COMMON_ISSUES.md](COMMON_ISSUES.md#esc-key-closes-the-game).
+
+### Global Hotkeys
+- **F1 / F11** - Toggle fullscreen
+- **ESC** - Pause game (in game state)
+
+## 📖 State Management Patterns
+
+### Simple State Switch
+```lua
+-- From menu to game
+GameState.switch(gameState)
+```
+
+### State Stack (Pause Menu)
+```lua
+-- Push pause menu (game continues in background)
+GameState.push(pauseMenu)
+
+-- Return to game
+GameState.pop()
+```
+
+### Passing Data Between States
+```lua
+-- Pass score to game over screen
+GameState.switch(gameOverState, score, highScore)
+
+-- In game over state:
+function gameOverState:enter(previous, score, highScore)
+  self.score = score
+  self.highScore = highScore
+end
+```
+
+## 🎯 Best Practices
+
+### Performance
+- Load assets in `state:enter()`, not `update()`
+- Unload assets in `state:leave()`
+- Use object pooling for bullets/particles
+- Profile with `--log` flag
+
+### Organization
+- One file per state
+- Keep states small and focused
+- Use OOP for game entities (Player, Enemy, etc.)
+- Separate rendering from logic
+
+### Asset Loading
+```lua
+function state:enter()
+  -- Show loading if needed
+  local assets = {"player.png", "enemy.png", "music.ogg"}
+  RL.BeginAssetLoading(#assets)
+  
+  for _, asset in ipairs(assets) do
+    RL.UpdateAssetLoading(asset)
+    -- Load asset...
+  end
+  
+  RL.EndAssetLoading()
+end
+```
+
+## 🐛 Debugging
+
+### Development Mode
+```bash
+ReiLua.exe --log --no-logo
+```
+- Shows console output
+- Skips splash screens
+- Fast iteration
+
+### Common Issues
+
+**Animation not showing:**
+- Check texture loaded: `if not texture then print("Failed!") end`
+- Verify frame size matches sprite sheet
+- Check animation is playing: `anim:play("idle")`
+
+**State not switching:**
+- Verify `GameState.registerEvents()` called in `RL.init()`
+- Check state has required functions (`:update()`, `:draw()`)
+- Use `print()` in `:enter()` to verify state switch
+
+**Assets not loading:**
+- Use relative paths: `"assets/player.png"` not `"C:/..."`
+- Check file exists with `RL.FileExists()`
+- View console with `--log` flag

+# Window Configuration Guide
+
+Complete guide for setting up window size, fullscreen, and window management in ReiLua-Enhanced.
+
+## Table of Contents
+- [Window Size](#window-size)
+- [Fullscreen Mode](#fullscreen-mode)
+- [Window Flags](#window-flags)
+- [Window States](#window-states)
+- [Complete Examples](#complete-examples)
+
+## Window Size
+
+### Initial Window Size
+
+Set window size when initializing:
+
+```lua
+-- Method 1: Default size (uses RayLib's default: 800x450)
+function RL.init()
+  RL.SetWindowTitle("My Game")
+end
+
+-- Method 2: Set specific size after init
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  RL.SetWindowSize({1280, 720})  -- 1280x720 window
+end
+
+-- Method 3: Manual InitWindow (in RL.config, advanced)
+function RL.config()
+  RL.InitWindow({1920, 1080}, "My Game")
+end
+```
+
+### Change Window Size During Runtime
+
+```lua
+-- Resize window to 1920x1080
+RL.SetWindowSize({1920, 1080})
+
+-- Get current window size
+local size = RL.GetScreenSize()
+print("Width: " .. size[1] .. ", Height: " .. size[2])
+
+-- Common resolutions
+RL.SetWindowSize({800, 600})    -- 4:3 ratio
+RL.SetWindowSize({1280, 720})   -- HD (720p)
+RL.SetWindowSize({1920, 1080})  -- Full HD (1080p)
+RL.SetWindowSize({2560, 1440})  -- QHD (1440p)
+RL.SetWindowSize({3840, 2160})  -- 4K (2160p)
+```
+
+### Resizable Window
+
+Allow users to resize the window:
+
+```lua
+function RL.init()
+  -- Enable window resizing
+  RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+  
+  -- Optional: Set min/max size constraints
+  RL.SetWindowMinSize({800, 600})
+  RL.SetWindowMaxSize({1920, 1080})
+end
+
+function RL.update(dt)
+  -- Check if window was resized
+  if RL.IsWindowResized() then
+    local size = RL.GetScreenSize()
+    print("Window resized to: " .. size[1] .. "x" .. size[2])
+    
+    -- Update your game viewport/camera if needed
+  end
+end
+```
+
+## Fullscreen Mode
+
+### Toggle Fullscreen
+
+```lua
+-- Simple toggle (F11 or F1 key)
+function RL.update(dt)
+  if RL.IsKeyPressed(RL.KEY_F11) then
+    RL.ToggleFullscreen()
+  end
+end
+
+-- The template already includes this with F1 and F11
+```
+
+### Set Fullscreen at Startup
+
+```lua
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  
+  -- Start in fullscreen mode
+  RL.SetWindowState(RL.FLAG_FULLSCREEN_MODE)
+end
+```
+
+### Borderless Fullscreen (Windowed Fullscreen)
+
+Better alternative to true fullscreen - faster alt-tab, no resolution change:
+
+```lua
+function RL.update(dt)
+  if RL.IsKeyPressed(RL.KEY_F11) then
+    RL.ToggleBorderlessWindowed()
+  end
+end
+
+-- Or at startup
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  RL.ToggleBorderlessWindowed()
+end
+```
+
+### Check Fullscreen Status
+
+```lua
+if RL.IsWindowFullscreen() then
+  print("Running in fullscreen")
+else
+  print("Running in windowed mode")
+end
+```
+
+### Different Fullscreen Modes
+
+```lua
+-- Method 1: True fullscreen (changes display resolution)
+RL.SetWindowState(RL.FLAG_FULLSCREEN_MODE)
+
+-- Method 2: Borderless windowed (keeps desktop resolution)
+RL.ToggleBorderlessWindowed()
+
+-- Method 3: Toggle between windowed and last fullscreen mode
+RL.ToggleFullscreen()
+```
+
+## Window Flags
+
+Window flags control various window behaviors. Set them before or after initialization.
+
+### Common Window Flags
+
+```lua
+-- VSync (synchronize with monitor refresh rate)
+RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+
+-- Fullscreen mode
+RL.SetWindowState(RL.FLAG_FULLSCREEN_MODE)
+
+-- Resizable window
+RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+
+-- Borderless window (no title bar)
+RL.SetWindowState(RL.FLAG_WINDOW_UNDECORATED)
+
+-- Always on top
+RL.SetWindowState(RL.FLAG_WINDOW_TOPMOST)
+
+-- Hidden window (start hidden)
+RL.SetWindowState(RL.FLAG_WINDOW_HIDDEN)
+
+-- Transparent window
+RL.SetWindowState(RL.FLAG_WINDOW_TRANSPARENT)
+
+-- High DPI support
+RL.SetWindowState(RL.FLAG_WINDOW_HIGHDPI)
+
+-- MSAA 4x antialiasing
+RL.SetWindowState(RL.FLAG_MSAA_4X_HINT)
+```
+
+### Combining Multiple Flags
+
+You can't OR flags in Lua, so set them individually:
+
+```lua
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  
+  -- Set multiple flags
+  RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+  RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+  RL.SetWindowState(RL.FLAG_MSAA_4X_HINT)
+end
+```
+
+### Check if Flag is Enabled
+
+```lua
+if RL.IsWindowState(RL.FLAG_WINDOW_RESIZABLE) then
+  print("Window is resizable")
+end
+
+if RL.IsWindowState(RL.FLAG_VSYNC_HINT) then
+  print("VSync is enabled")
+end
+```
+
+### Clear Window Flags
+
+```lua
+-- Remove a specific flag
+RL.ClearWindowState(RL.FLAG_WINDOW_TOPMOST)
+
+-- Remove resizable flag
+RL.ClearWindowState(RL.FLAG_WINDOW_RESIZABLE)
+```
+
+## Window States
+
+### Maximize/Minimize
+
+```lua
+-- Maximize window (fill screen without fullscreen)
+RL.MaximizeWindow()
+
+-- Minimize window (to taskbar)
+RL.MinimizeWindow()
+
+-- Restore window
+RL.RestoreWindow()
+```
+
+### Check Window State
+
+```lua
+-- Check if window is maximized
+if RL.IsWindowMaximized() then
+  print("Window is maximized")
+end
+
+-- Check if window is minimized
+if RL.IsWindowMinimized() then
+  print("Window is minimized")
+end
+
+-- Check if window is focused
+if RL.IsWindowFocused() then
+  print("Window has focus")
+end
+
+-- Check if window is hidden
+if RL.IsWindowHidden() then
+  print("Window is hidden")
+end
+```
+
+### Window Position
+
+```lua
+-- Set window position on screen
+RL.SetWindowPosition({100, 100})  -- x, y from top-left of screen
+
+-- Get current window position
+local pos = RL.GetWindowPosition()
+print("Window at: " .. pos[1] .. ", " .. pos[2])
+
+-- Center window on monitor
+local monitorWidth = RL.GetMonitorWidth(0)
+local monitorHeight = RL.GetMonitorHeight(0)
+local windowSize = RL.GetScreenSize()
+
+RL.SetWindowPosition({
+  (monitorWidth - windowSize[1]) / 2,
+  (monitorHeight - windowSize[2]) / 2
+})
+```
+
+### Monitor Information
+
+```lua
+-- Get number of monitors
+local monitorCount = RL.GetMonitorCount()
+
+-- Get monitor dimensions
+local width = RL.GetMonitorWidth(0)   -- Monitor 0 (primary)
+local height = RL.GetMonitorHeight(0)
+
+-- Get monitor name
+local name = RL.GetMonitorName(0)
+print("Monitor: " .. name)
+
+-- Get current monitor
+local currentMonitor = RL.GetCurrentMonitor()
+```
+
+## Complete Examples
+
+### Example 1: Game with Options Menu
+
+```lua
+-- config.lua
+local Config = {
+  resolution = {1280, 720},
+  fullscreen = false,
+  vsync = true,
+  resizable = true
+}
+
+function Config.apply()
+  -- Apply resolution
+  RL.SetWindowSize(Config.resolution)
+  
+  -- Apply fullscreen
+  if Config.fullscreen then
+    if not RL.IsWindowFullscreen() then
+      RL.ToggleBorderlessWindowed()
+    end
+  else
+    if RL.IsWindowFullscreen() then
+      RL.ToggleBorderlessWindowed()
+    end
+  end
+  
+  -- Apply VSync
+  if Config.vsync then
+    RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+  else
+    RL.ClearWindowState(RL.FLAG_VSYNC_HINT)
+  end
+end
+
+-- main.lua
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  
+  -- Apply saved config
+  Config.apply()
+  
+  -- Make window resizable
+  if Config.resizable then
+    RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+    RL.SetWindowMinSize({800, 600})
+  end
+end
+```
+
+### Example 2: Adaptive Resolution
+
+```lua
+function RL.init()
+  RL.SetWindowTitle("My Game")
+  
+  -- Get monitor size
+  local monitorWidth = RL.GetMonitorWidth(0)
+  local monitorHeight = RL.GetMonitorHeight(0)
+  
+  -- Use 80% of monitor size
+  local width = math.floor(monitorWidth * 0.8)
+  local height = math.floor(monitorHeight * 0.8)
+  
+  RL.SetWindowSize({width, height})
+  
+  -- Center window
+  RL.SetWindowPosition({
+    (monitorWidth - width) / 2,
+    (monitorHeight - height) / 2
+  })
+  
+  RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+end
+```
+
+### Example 3: Dynamic Fullscreen Toggle
+
+```lua
+local isFullscreen = false
+
+function toggleFullscreen()
+  isFullscreen = not isFullscreen
+  
+  if isFullscreen then
+    -- Save windowed size before going fullscreen
+    windowedSize = RL.GetScreenSize()
+    windowedPos = RL.GetWindowPosition()
+    
+    -- Go fullscreen
+    RL.ToggleBorderlessWindowed()
+  else
+    -- Restore windowed mode
+    RL.ToggleBorderlessWindowed()
+    
+    -- Restore previous size and position
+    if windowedSize then
+      RL.SetWindowSize(windowedSize)
+      RL.SetWindowPosition(windowedPos)
+    end
+  end
+end
+
+function RL.update(dt)
+  if RL.IsKeyPressed(RL.KEY_F11) then
+    toggleFullscreen()
+  end
+end
+```
+
+### Example 4: Resolution Presets
+
+```lua
+local resolutions = {
+  {name = "HD", size = {1280, 720}},
+  {name = "Full HD", size = {1920, 1080}},
+  {name = "QHD", size = {2560, 1440}},
+  {name = "Custom", size = {800, 600}}
+}
+
+local currentResolution = 2  -- Start with Full HD
+
+function changeResolution(index)
+  currentResolution = index
+  local res = resolutions[index]
+  
+  if RL.IsWindowFullscreen() then
+    -- Exit fullscreen first
+    RL.ToggleBorderlessWindowed()
+  end
+  
+  RL.SetWindowSize(res.size)
+  
+  -- Center window after resize
+  local monitorWidth = RL.GetMonitorWidth(0)
+  local monitorHeight = RL.GetMonitorHeight(0)
+  RL.SetWindowPosition({
+    (monitorWidth - res.size[1]) / 2,
+    (monitorHeight - res.size[2]) / 2
+  })
+  
+  print("Resolution changed to: " .. res.name)
+end
+
+-- In options menu:
+function drawResolutionOptions()
+  for i, res in ipairs(resolutions) do
+    local color = (i == currentResolution) and RL.YELLOW or RL.WHITE
+    local text = res.name .. " (" .. res.size[1] .. "x" .. res.size[2] .. ")"
+    -- Draw option...
+  end
+end
+```
+
+### Example 5: Template Integration
+
+Update your template's `main.lua`:
+
+```lua
+-- Game configuration
+local GAME_TITLE = "My Game"
+local WINDOW_WIDTH = 1280
+local WINDOW_HEIGHT = 720
+local TARGET_FPS = 60
+local START_FULLSCREEN = false  -- Start in fullscreen?
+
+function RL.init()
+  -- Window setup
+  RL.SetWindowTitle(GAME_TITLE)
+  RL.SetWindowSize({WINDOW_WIDTH, WINDOW_HEIGHT})
+  RL.SetTargetFPS(TARGET_FPS)
+  
+  -- Window flags
+  RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+  RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+  
+  -- Start fullscreen if configured
+  if START_FULLSCREEN then
+    RL.ToggleBorderlessWindowed()
+  end
+  
+  -- Disable ESC exit key
+  RL.SetExitKey(0)
+  
+  -- Rest of initialization...
+end
+
+function RL.update(delta)
+  -- Global hotkeys
+  if RL.IsKeyPressed(RL.KEY_F1) or RL.IsKeyPressed(RL.KEY_F11) then
+    RL.ToggleBorderlessWindowed()
+  end
+  
+  -- Handle window resize
+  if RL.IsWindowResized() then
+    local newSize = RL.GetScreenSize()
+    print("Window resized to: " .. newSize[1] .. "x" .. newSize[2])
+    -- Update your camera/viewport here if needed
+  end
+  
+  -- Rest of update...
+end
+```
+
+## Quick Reference
+
+### Most Used Functions
+
+```lua
+-- Size
+RL.SetWindowSize({width, height})
+RL.GetScreenSize()
+
+-- Fullscreen
+RL.ToggleBorderlessWindowed()  -- Recommended
+RL.ToggleFullscreen()           -- Alternative
+RL.IsWindowFullscreen()
+
+-- Flags
+RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+
+-- State
+RL.MaximizeWindow()
+RL.MinimizeWindow()
+RL.IsWindowResized()
+RL.IsWindowFocused()
+
+-- Position
+RL.SetWindowPosition({x, y})
+RL.GetWindowPosition()
+
+-- Monitor
+RL.GetMonitorWidth(0)
+RL.GetMonitorHeight(0)
+```
+
+## Tips and Best Practices
+
+### Performance
+- Use `RL.FLAG_VSYNC_HINT` to prevent screen tearing
+- Use borderless fullscreen instead of true fullscreen for faster alt-tab
+- Check `IsWindowResized()` before recalculating viewport/camera
+
+### User Experience
+- Always provide a fullscreen toggle (F11 is standard)
+- Save window size/position preferences
+- Offer resolution presets in options menu
+- Make window resizable for flexibility
+
+### Compatibility
+- Test different resolutions and aspect ratios
+- Use `GetMonitorWidth/Height()` to detect screen size
+- Don't hardcode UI positions - use percentages or anchors
+- Support both windowed and fullscreen modes

+## 🎮 Quick Usage
+
+### Set Window Size
+```lua
+-- In main.lua configuration
+local WINDOW_WIDTH = 1920
+local WINDOW_HEIGHT = 1080
+
+-- Or at runtime
+RL.SetWindowSize({1920, 1080})
+```
+
+### Enable Fullscreen
+```lua
+-- Toggle with F1 or F11 (already in template)
+
+-- Or start in fullscreen

+
+-- Or manually
+RL.ToggleBorderlessWindowed()  -- Borderless (recommended)
+RL.ToggleFullscreen()           -- True fullscreen
+```
+
+### Make Window Resizable
+```lua
+-- Already enabled in template!
+RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+RL.SetWindowMinSize({800, 600})  -- Optional min size
+```
+
+### Common Resolutions
+```lua
+RL.SetWindowSize({1280, 720})   -- HD (720p)
+RL.SetWindowSize({1920, 1080})  -- Full HD (1080p)
+RL.SetWindowSize({2560, 1440})  -- QHD (1440p)
+RL.SetWindowSize({3840, 2160})  -- 4K (2160p)
+```
+
+### Window Flags
+```lua
+RL.SetWindowState(RL.FLAG_VSYNC_HINT)          -- VSync (in template)
+RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)    -- Resizable (in template)
+RL.SetWindowState(RL.FLAG_FULLSCREEN_MODE)     -- Fullscreen
+RL.SetWindowState(RL.FLAG_WINDOW_TOPMOST)      -- Always on top
+RL.SetWindowState(RL.FLAG_MSAA_4X_HINT)        -- Antialiasing
+```

+## 💡 Best Practices
+
+### Recommended Settings
+```lua
+function RL.init()
+  -- Good default settings
+  RL.SetWindowSize({1280, 720})
+  RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+  RL.SetWindowState(RL.FLAG_WINDOW_RESIZABLE)
+  RL.SetWindowMinSize({800, 600})
+end
+```
+
+### Fullscreen Toggle
+```lua
+-- Use borderless windowed (faster alt-tab, no resolution change)
+if RL.IsKeyPressed(RL.KEY_F11) then
+  RL.ToggleBorderlessWindowed()
+end
+```
+
+### Responsive Design
+```lua
+function RL.update(dt)
+  if RL.IsWindowResized() then
+    local size = RL.GetScreenSize()
+    -- Update your UI/camera to new size
+    updateViewport(size[1], size[2])
+  end
+end
+```
+
+### Adaptive Resolution
+```lua
+-- Auto-size to 80% of monitor
+local monitorW = RL.GetMonitorWidth(0)
+local monitorH = RL.GetMonitorHeight(0)
+RL.SetWindowSize({
+  math.floor(monitorW * 0.8),
+  math.floor(monitorH * 0.8)
+})
+
+-- Center window
+local size = RL.GetScreenSize()
+RL.SetWindowPosition({
+  (monitorW - size[1]) / 2,
+  (monitorH - size[2]) / 2
+})
+```
+
+## 🎯 Common Use Cases
+
+### 1. Options Menu
+```lua
+-- Store in config
+config.resolution = {1920, 1080}
+config.fullscreen = false
+
+-- Apply settings
+if config.fullscreen then
+  RL.ToggleBorderlessWindowed()
+else
+  RL.SetWindowSize(config.resolution)
+end
+```
+
+### 2. Multiple Resolution Presets
+```lua
+local resolutions = {
+  {1280, 720},   -- HD
+  {1920, 1080},  -- Full HD
+  {2560, 1440}   -- QHD
+}
+
+function changeResolution(index)
+  RL.SetWindowSize(resolutions[index])
+end
+```
+
+### 3. Game Jam Quick Setup
+```lua
+-- Fast setup for prototyping
+RL.SetWindowSize({1280, 720})
+RL.SetWindowState(RL.FLAG_VSYNC_HINT)
+RL.SetExitKey(0)  -- Disable ESC exit
+```

+assets/
+├── images/
+│   ├── player.png
+│   ├── enemy.png
+│   └── background.png
+├── sounds/
+│   ├── jump.wav

+
+## Sprite Sheet Guidelines
+
+### Grid-Based Animations
+- Use equal-sized frames arranged in a grid
+- Frames are read left-to-right, top-to-bottom
+- Example: 32x32 pixel frames
+
+### Example Layout
+```
+Frame 1  Frame 2  Frame 3  Frame 4
+Frame 5  Frame 6  Frame 7  Frame 8
+```
+
+### Recommended Sizes
+- Player: 32x32 or 64x64
+- Enemies: 32x32
+- Effects: 16x16, 32x32, or 64x64
+- Backgrounds: Match your game resolution
+
+## Audio Guidelines
+
+### Sound Effects
+- Format: WAV (uncompressed) or OGG (compressed)
+- Short sounds (< 2 seconds): Use WAV
+- Length: Keep under 5 seconds for quick loading
+
+### Music
+- Format: OGG (recommended for size)
+- Use streaming (LoadMusicStream) for music
+- Sample rate: 44100 Hz recommended
+
+## Loading Assets
+
+### In Lua
+```lua
+-- Images
+local playerImg = RL.LoadTexture("assets/images/player.png")
+
+-- Sounds
+local jumpSound = RL.LoadSound("assets/sounds/jump.wav")
+
+-- Music (streaming)
+local music = RL.LoadMusicStream("assets/music/theme.ogg")
+
+-- Fonts
+local font = RL.LoadFont("assets/fonts/game_font.ttf")
+```
+
+### With Loading Screen
+```lua
+local assetsToLoad = {
+  "assets/images/player.png",
+  "assets/sounds/jump.wav",
+  "assets/music/theme.ogg"
+}
+
+RL.BeginAssetLoading(#assetsToLoad)
+for _, asset in ipairs(assetsToLoad) do
+  RL.UpdateAssetLoading(asset)
+  -- Load the asset...
+end
+RL.EndAssetLoading()
+```
+
+## Tips
+
+- Keep asset sizes reasonable (< 2MB per file for quick loading)
+- Use PNG for images with transparency
+- Use JPG for photos/backgrounds (smaller size)
+- Optimize images before adding to game
+- Test loading times during development
