-+epple2+ is an emulator of the *Apple ][* and *Apple ][ plus*
-computers from Apple, Inc. It strives to faithfully simulate
-much of the internal workings of the original Apple ][,
-including the individual cycles of the 6502 CPU, and the
-NTSC video signal generation, including the ``strange orange
-line'', other color anomalies, and the ``floating data bus.''
-_Understanding the Apple ][_, by Jim Sather, is the primary
-source for information about the internals of the Apple ][.
-
-The CPU and video timings are synchronized, and the emulator
-is designed to run at the same speed as the original
-machine (if your computer is fast enough). It also emulates
-several different types of television screens and monitors
-for the display.
-
-It includes emulation of a Disk ][ controller card, a ROM
-firmware card, and a RAM Language card, as well as a
-simple clock card.
-
-+epple2+ is written in C++, and is designed to be buildable
-on Linux, Mac, or Windows (mingw). http://www.libsdl.org/[SDL]
-is the only dependency.

-+epple2+ is released under GPLv3.

+
+`epple2` is an emulator of the **Apple ][** and **Apple ][ plus**
+computers from Apple, Inc.
+
+---
+
+The fundamental principle of `epple2` is to accurately and faithfully
+emulate the behavior of the original Apple ][ machines, including the
+internal workings, as much as practical.
+
+Features of the emulation include:
+* individual cycles of the 6502 CPU
+* NTSC video signal generation
+* displaying the *strange orange line*
+* other display color anomalies
+* floating data bus
+* Disk ][ Logic State Sequencer
+* read copy-protected disks
+* read/write half- and quarter-tracks
+* configurable RAM chips
+* cassette tape interface
+
+The CPU and video timings are synchronized, and the emulator
+is designed to run at the same speed as the original
+machine (about 1MHz). It also emulates a television screen,
+and color and monochrome monitors, for the display.
+
+It includes emulation of the **Disk ][** controller card,
+the ROM firmware card, and the RAM Language Card, as well
+as a simple clock card.
+
+The primary source for information about the internals of the
+Apple ][ is *Understanding the Apple ][*, by Jim Sather.
+
+`epple2` is written in C++, and is designed to be buildable
+on Linux, Mac, or Windows (mingw).
+[SDL](http://www.libsdl.org/) is the only dependency.
