+# 🛠️ WoW Modernization Tool v2.0
+
+This is a major update focused on **easier setup, safer updates, automatic component refreshes and new optional client improvements**.
+
+Existing users do **not** need to reinstall WoW. Select your current game folder, review your options and click **Apply Setup & Tweaks**.
+
+## 🔄 Automatic Updates & Offline Protection
+
+Supported components can now be refreshed directly from their upstream releases when you apply the setup.
+
+If an online update is unavailable, the tool will keep a valid installed version or use a bundled known-good fallback when available. Existing working files are preserved whenever possible instead of being replaced unnecessarily.
+
+## 🎮 Rendering & DXVK
+
+Renderer selection is now simpler:
+
+- **VanillaFixes — DirectX 9** *(default)* — uses WoW's native DirectX 9 renderer.
+- **VanillaFixes + DXVK — Vulkan** — translates DirectX 9 to Vulkan and may provide smoother frame pacing on modern systems.
+
+The bundled DXVK version is now **2.6.1 x86** with a configuration aligned with VanillaFixes.
+
+Switching back to DirectX 9 now safely moves unknown existing D3D9 wrapper files out of the WoW root instead of deleting them.
+
+## 🧩 New & Updated Plugins
+
+- **ClassicAPI** — adds newer WoW API functions so compatible modern addons can work on the Vanilla client.
+- **AuctionQueryThrottle** — removes the fixed Auction House query delay for much faster searches.
+- **VanillaMultiMonitorFix** — improves resolution, refresh-rate and monitor detection on multi-monitor setups.
+- **Interact** — adds a modern interaction key for nearby NPCs, objects, gathering nodes and loot.
+- **WorldMarkers 0.7.1** — updated optional world-marker support.
+- **WeirdPerformance 0.7.3** — updated engine/runtime optimizations for client smoothness and reduced overhead.
+
+## ⚙️ New Client Tweaks
+
+- **Unlimited AddOn Script Memory** — removes WoW's AddOn memory limit.
+- **Cross-Faction Resurrection Fix** — improves resurrection handling for released cross-faction players.
+- **Custom Glues Patch** — enables custom login and character-selection interface modifications.
+- **Automatically Clear WDB** — clears stale WDB cache data and safely manages the WDB blocker.
+- **SuperWoW conflict prevention** — equivalent vanilla-tweaks patches are automatically skipped when SuperWoW already handles FoV, Sound Channels, Auto-Loot or Background Sound.
+
+## 🌙 New Visual Mods
+
+All visual mods are optional and disabled by default.
+
+- **Bluemoon Patch** — restores the rare blue moon visual effect.
+- **Darker Nights** — makes nighttime environments darker and more atmospheric.
+- **Pretty Night Sky** — replaces the Vanilla night sky with a more detailed starry sky.
+- **Epoch Water** — replaces the original Vanilla water textures.
+- **Fog Pushback** — pushes environmental fog farther away for clearer long-distance visibility.
+- **Pink Herbs** — makes herb nodes bright pink/purple so they are easier to spot.
+
+## 🔊 New Audio Mods
+
+All audio mods are optional and disabled by default.
+
+- **NoErrorSounds** — removes many repetitive spell fizzle/error and interface sounds.
+- **FishPing** — replaces the fishing bite sound with a much easier-to-hear ping.
+- **Warlock Muted Demons** — mutes many repetitive Warlock demon voice lines.
+
+## 🔐 AutoLogin Security Improvements
+
+When **AutoLogin + Nampower** are enabled together, Modernization Tool now automatically creates or reuses the Windows user encryption key required by Nampower.
+
+AutoLogin also enables password encryption by default when encryption is available. Existing user encryption keys are never replaced, and an explicit user choice to disable AutoLogin encryption is preserved.
+
+## 💾 Installer & Safety Improvements
+
+- Settings are remembered separately for each WoW installation.
+- Manually added entries and comments in `dlls.txt` are preserved.
+- Downloaded/bundled DLLs are validated before installation.
+- Important replacements are performed transactionally to reduce the risk of partial installs.
+- Existing valid files are kept when an upstream download fails.
+- Large visual mods are not re-downloaded when the installed revision is already current.
+- Legacy Modernization Tool files are cleaned up safely.
+- The selected game folder is validated before changes are made.
+
+## 🚀 Launcher Improvements
+
+After installation, **Play Modernized WoW** is created both:
+
+- in the WoW game folder;
+- on the Windows Desktop.
+
+Use either shortcut to launch the modernized client.
+
+## 📦 Notable Bundled / Known-Good Versions
+
+- VanillaFixes **1.5.3**
+- DXVK **2.6.1 x86**
+- Nampower **4.6.1**
+- ClassicAPI **1.12.7**
+- AuctionQueryThrottle **1.2.0**
+- UnitXP_SP3 **v90**
+- SuperWoW **2.2**
+- VanillaHelpers **1.1.2**
+- WeirdPerformance **0.7.3**
+- WorldMarkers **0.7.1**
+- VanillaMultiMonitorFix **0.2**
+- Interact **1.0.4**
+
+## ✅ Updating from v1.1
+
+Download **WoW_Modernization_Tool.exe**, select your existing WoW installation and click **Apply Setup & Tweaks**.
+
+A complete WoW reinstall is not required.
