+# Compile Instructions
+
+## Visual Studio (`.sln`)
+
+1. Open `MinecraftConsoles.sln` in Visual Studio 2022.
+2. Set `Minecraft.Client` as the Startup Project.
+3. Select configuration:
+   - `Debug` (recommended), or
+   - `Release`
+4. Select platform: `Windows64`.
+5. Build and run:
+   - `Build > Build Solution` (or `Ctrl+Shift+B`)
+   - Start debugging with `F5`.
+
+## CMake (Windows x64)
+
+Configure (use your VS Community instance explicitly):
+
+```powershell
+cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_GENERATOR_INSTANCE="C:/Program Files/Microsoft Visual Studio/2022/Community"
+```
+
+Build Debug:
+
+```powershell
+cmake --build build --config Debug --target MinecraftClient
+```
+
+Build Release:
+
+```powershell
+cmake --build build --config Release --target MinecraftClient
+```
+
+Run executable:
+
+```powershell
+cd .\build\Debug
+.\MinecraftClient.exe
+```
+
+Notes:
+- The CMake build is Windows-only and x64-only.
+- Post-build asset copy is automatic for `MinecraftClient` in CMake (Debug and Release variants).
+- The game relies on relative paths (for example `Common\Media\...`), so launching from the output directory is required.
