+# Detours (prebuilt package)
+
+This folder contains a **prebuilt** copy of the Microsoft Detours library, packaged in the layout expected by the top-level CMake build.
+
+Expected layout:
+
+- `include/` (Detours headers)
+- `lib/<arch>/<config>/detours.lib`
+  - `<arch>`: `x86`, `x64`, `arm64`
+  - `<config>`: `Debug`, `Release`
+
+## Regenerating / updating
+
+If this folder is missing (or you need to update Detours), run from the repo root:
+
+```powershell
+# Builds & packages x86 + x64 + arm64 into dependencies/detours
+pwsh -ExecutionPolicy Bypass -File .\scripts\detours-all.ps1
+```
+
+The Detours source is cloned into `dependencies/sources/detours`.
