+ The Emularity: An Example Computer Loader
+ For use with The Emularity, downloadable at http://www.emularity.com/
+
+ SIMPLE STEPS for trying an emulated computer ("PC-DOS 1.0" for the
+ IBM PC Model 5150).
+
+ * Check out this repository in your browser-accessible directory;
+   this file as well as es6-promise.js, browserfs.min.js and loader.js
+   are required. The logo and images directories are optional, but the
+   splash screen looks quite a lot better when they're available.
+
+ * Download the PCE.js IBM PC emulator from
+   https://9game.oss-us-west-1.aliyuncs.com/mini-ibmpc/pcejs-ibmpc.min.js
+   It's a slightly modified version from the NPM one:
+   https://www.npmjs.com/package/pcejs-ibmpc
+ 
+ * Download the original IBM PC BIOS package
+   https://9game.oss-us-west-1.aliyuncs.com/mini-ibmpc/rom-ibmpc-1981.zip
+
+ * Download the configuration file, it's a minimized version for easiler
+   to make your configuration based on that
+   https://9game.oss-us-west-1.aliyuncs.com/mini-ibmpc/pce-mini.cfg
+
+ * Download PC-DOS 1.0 disk image
+   https://9game.oss-us-west-1.aliyuncs.com/mini-ibmpc/pcdos1_0.pfdc
+
+ * Visit your example_computer.html file with a modern
+   Javascript-capable browser.
