 ### Dependencies
 
+Any `make` command depends on GNU make (`gmake`) and is expected to be run using it. This usually means using `make` on most GNU/Linux distros, or `gmake` on other non-GNU systems.

 All `make all*` targets depend on a GNU-compatible C toolchain capable of generating x86-64 ELF objects. Usually `gcc/binutils` or `clang/llvm/lld` provided by any x86-64 UNIX like (including Linux) distribution will suffice.
 
 Additionally, building an ISO with `make all` requires `xorriso`, and building a HDD/USB image with `make all-hdd` requires `sgdisk` (usually from `gdisk` or `gptfdisk` packages) and `mtools`.
