+NetBSD support in htop(1)
+===
+
+This implementation utilizes kvm_getprocs(3), sysctl(3), etc, eliminating the
+need for mount_procfs(8) with Linux compatibility enabled.
+
+The implementation was initially based on the OpenBSD support in htop(1).
+
+Notes on NetBSD curses
+---
+
+NetBSD is one of the last operating systems to use and maintain its own
+implementation of Curses.
+
+htop(1) can be compiled against either ncurses or NetBSD's curses(3).
+In order for NetBSD's libcurses to be used, htop(1) must be configured with
+`--disable-unicode`. This is necessary because htop(1) with Unicode enabled
+directly accesses ncurses's cchar_t struct, which has different contents
+in NetBSD's curses.
+
+Versions of libcurses in NetBSD 9 and prior have no mouse support
+(this is an ncurses extension). Newer versions contain no-op mouse functions
+for compatibility with ncurses.
+
+What needs improvement
+---
+
+* Kernel and userspace threads are not displayed or counted -
+ maybe look at NetBSD top(1).
+* Support for compiling using libcurses's Unicode support.
+* Support for fstat(1) (view open files, like lsof(8) on Linux).
+* Support for ktrace(1) (like strace(1) on Linux).
