+Built from `trumank/mint` main (v0.2.10) with the **default `hook` feature enabled**:
 
 ```bash
-cargo +nightly-2026-04-24 build --package mint --no-default-features --release
+# build-time deps (NOT needed at runtime)
+apt install -y mingw-w64
+rustup target add x86_64-pc-windows-gnu --toolchain nightly-2026-04-24

+cargo +nightly-2026-04-24 build --package mint --release
 ```
 
-The default `hook` feature is a Windows game-injection cdylib (`x86_64-pc-windows-gnu`) and is
-intentionally excluded on Linux. Binary is stripped.
+The Linux MINT executable is built with the default `hook` feature enabled.
+The hook itself is cross-compiled for `x86_64-pc-windows-gnu` because
+Deep Rock Galactic runs as a Windows application under Proton.
+MinGW-w64 is therefore required **at build time only, not at runtime** —
+the hook DLL is embedded into the Linux binary via Cargo artifact dependency
+(`include_bytes!(env!("CARGO_CDYLIB_FILE_HOOK_hook"))`) and written by MINT
+itself to `FSD/Binaries/Win64/x3daudio1_7.dll` when installing mods.
+Binary is stripped.
