+## `ncurses`
+
+Thin bindings for the system `ncurses` or `curses` library.
+
+Supported targets:
+
+- macOS
+- Linux
+- BSD and Solaris targets that provide a compatible curses library
+- Windows currently reports `ncurses.is_supported() == false`
+
+Most functions return `ncurses.ok` on success and `ncurses.err` on failure.
+`getch()` and `wgetch()` return an `int`. Compare special keys with
+`ncurses.key_*`.
+
+```v
+import ncurses
+
+fn main() {
+	if !ncurses.is_supported() {
+		return
+	}
+	stdscr := ncurses.initscr()
+	defer {
+		ncurses.endwin()
+	}
+	ncurses.cbreak()
+	ncurses.noecho()
+	ncurses.keypad(stdscr, true)
+	ncurses.addstr('Press a key...')
+	ncurses.refresh()
+
+	key := ncurses.getch()
+	ncurses.mvaddstr(1, 0, 'Key code: ${key}')
+	ncurses.refresh()
+	ncurses.getch()
+}
+```
+
+Use `newwin`, `box`, `waddstr`, `wrefresh`, and `wgetch` for additional windows.
+Use `start_color`, `init_pair`, and `color_pair` for color attributes.
