 DESCRIPTION
 -----------
-sfm is a lightweight, terminal-based file manager written entirely in
-POSIX sh. It runs in your terminal with no external dependencies beyond
-standard Unix tools (ls, awk, tput, stty, mv, cp, rm). Designed to be
-fast, flicker-free, and keyboard-driven with a vim-inspired key layout.
+sfm is a lightweight, terminal-based file manager with a vim-inspired
+key layout. The primary version is a fast C++ binary that works with
+both ncurses and netbsd-curses. A portable POSIX sh version (sfm.sh) is
+also included, requiring only standard Unix tools (ls, awk, tput, stty,
+mv, cp, rm).
  
  
 REQUIREMENTS
 ------------
+C++ version (sfm):
+- A curses library: ncursesw, ncurses, or netbsd-curses (libcurses)
+- A C++17 compiler (g++ or compatible)
+
+Shell version (sfm.sh):
 - A POSIX-compatible shell (sh, dash, bash, etc.)
 - Standard Unix tools: ls, awk, tput, stty, cp, mv, rm, mkdir, touch
+
+Both versions:
 - Optional: wl-copy / xclip / xsel / pbcopy  (for clipboard support)
 - Optional: mpv, vlc, feh, zathura, etc.     (for smart file opening)
 - Optional: readlink                         (for symlink display)
