 ***THIS IS AN UNOFFICIAL BUILD SCRIPT!***
 
 If you run into an issue with this build script, make an issue here. Don't bug Anthropic about it - they already have enough on their plates.
 
+# Claude Desktop for Fedora 43
+
+This is a modified version of the Claude Desktop build script, fixed to work on **Fedora 43** (Wayland/KDE Plasma).
+
+**Fixes in this version:**
+- **Fedora 43 Support**: Updated dependencies and build process
+- **Google Sign-In Fixed**: Implemented a native module stub to allow Google authentication to work
+- **Layout Fixes**: Fixed window scaling and maximizing glitches
+- **Titlebar Gap Fixed (v8)**: Root cause fix - patches titlebar height constants from 36px to 0
+- **Auto-Update**: Script automatically downloads the latest Claude Desktop version
+
 # Claude Desktop for Linux
 
 This project was inspired by [k3d3's claude-desktop-linux-flake](https://github.com/k3d3/claude-desktop-linux-flake) and their [Reddit post](https://www.reddit.com/r/ClaudeAI/comments/1hgsmpq/i_successfully_ran_claude_desktop_natively_on/) about running Claude Desktop natively on Linux. Their work provided valuable insights into the application's structure and the native bindings implementation.
 
-And now by me, via [Aaddrick's claude-desktop-debian](https://github.com/aaddrick/claude-desktop-debian), modified to work for Fedora 41.

+
+## Fedora Package (Updated for latest version!)
+
+For Fedora-based distributions you can build and install Claude Desktop using the provided build script.
 
-## 1. Fedora Package (New!)
+**What's New (v8):**
 
-For Fedora-based distributions you can build and install Claude Desktop using the provided build script (updated):
+- **Titlebar gap eliminated (ROOT CAUSE FIX)** - Patches height constants (`?0:36` -> `?0:0`) in the bundled JavaScript
+- **Why v8 works**: Claude Desktop reserves 36px for titlebar via ternary patterns. Patching these to 0 eliminates the gap at source.
+- **Auto-download latest version** - Script fetches the latest Claude Desktop automatically
+- **Native title bar support** - No more double title bar issue
+- **Fedora 43 Wayland/KDE compatibility** - Automatic environment configuration
