 = kgio - kinder, gentler I/O for Ruby
 
-kgio provides non-blocking I/O methods for Ruby without raising
-exceptions on EAGAIN and EINPROGRESS.  It is intended for use with the
-unicorn Rack server, but may be used by other applications (that run on
-Unix-like platforms).
+This is a legacy project, do not use it for new projects.  Ruby
+2.3 and later should make this obsolete.  kgio provides
+non-blocking I/O methods for Ruby without raising exceptions on
+EAGAIN and EINPROGRESS.
 
 == Features
 
 * Can avoid expensive exceptions on common EAGAIN/EINPROGRESS errors,
   returning :wait_readable or :wait_writable instead.
   These exceptions got more expensive to hit under Ruby 1.9.2
   (but were fixed in Ruby 1.9.3 and later to 1.9.1 performance levels,
-   which were still bad)
+  which were still bad)
 
 * Returns the unwritten portion of the string on partial writes,
   making it ideal for buffering unwritten data.
 
 * May call any method defined to be "kgio_wait_writable" or
   "kgio_wait_readable" methods to allow socket/pipe objects to make custom
   callbacks (such as adding the file descriptor to a poll set and yielding
   the current Fiber).
 
-* Uses
-  {accept4}[http://kernel.org/doc/man-pages/online/pages/man2/accept4.2.html]
-  on new GNU/Linux systems to avoid unnecessary fcntl() calls
+* Uses {accept4}[http://man7.org/linux/man-pages/man2/accept4.2.html]
+  on newer GNU/Linux systems to avoid unnecessary fcntl() calls
 
 * Uses MSG_DONTWAIT on GNU/Linux to further avoid unnecessary fcntl() calls
 
 * Compatible with existing Ruby IO objects and Ruby threading.
