-### Windows - Quick Flash

-1. **Download the SledLink folder** to your computer from GitHub
-2. **Extract the ZIP file** to a convenient location
-3. **Connect your controller** via USB cable to your computer
-4. **Double-click** `FlashFirmware.bat` in the main folder
-5. **Select your controller type:**
-   - Type `1` if flashing a SLED Controller (with encoder)
-   - Type `2` if flashing a JUDGE Controller (display only)
-6. **Flash happens automatically** - takes about 10 seconds
-7. **Done!** Your controller restarts automatically
-
-That's it! Your system is now ready to use.
-
-### What is "Flashing"?
-
-Flashing writes the firmware directly to your controller's memory using pre-compiled binaries. It's much faster than compiling (10 seconds vs 60+ seconds) and requires no additional software beyond Windows.
+Firmware is compiled fresh from source code during upload. This ensures compatibility with your system and allows for easy customization.
