[PATCH] EmulatorPkg: Update package level Readme.md

[Ruiyu Ni <ruiyu.ni@intel.com>]

Since the emulator under Windows is enabled, the patch changes
README to include the information of emulator under Windows.
It also changes README to Readme.md for better looking.

+## Overview
+
+EmulatorPkg provides an environment where a UEFI environment can be
+emulated under an environment where a full UEFI compatible
+environment is not possible.  (For example, running under an OS
+where an OS process hosts the UEFI emulation environment.)
+
+https://github.com/tianocore/tianocore.github.io/wiki/EmulatorPkg
+
+## Status
+
+* Builds and runs under
+  *  a posix-like environment with X windows
+      - Linux
+      - OS X
+  *  Windows environment
+      - Win10 (verified)
+      - Win8 (not verified)
+
+## How to Build & Run
+**You can use the following command to build.**
+  * 32bit emulator in Windows:
+
+    `build -p EmulatorPkg\EmulatorPkg.dsc -t VS2017 -D WIN_SEC_BUILD -a IA32`
+
+  * 64bit emulator in Windows:
+
+    `build -p EmulatorPkg\EmulatorPkg.dsc -t VS2017 -D WIN_SEC_BUILD -a X64`
+
+  * 32bit emulator in Linux:
+
+    `build -p EmulatorPkg\EmulatorPkg.dsc -t GCC5 -D UNIX_SEC_BUILD -a IA32`
+
+  * 64bit emulator in Linux:
+
+    `build -p EmulatorPkg\EmulatorPkg.dsc -t GCC5 -D UNIX_SEC_BUILD -a X64`
+
+**You can start/run the emulator using the following command:**
+  * 32bit emulator in Windows:
+
+    `cd Build\EmulatorIA32\DEBUG_VS2017\IA32\ && WinHost.exe`
+
+  * 64bit emulator in Windows:
+
+    `cd Build\EmulatorX64\DEBUG_VS2017\X64\ && WinHost.exe`
+
+  * 32bit emulator in Linux:
+
+    `cd Build/EmulatorIA32/DEBUG_GCC5/IA32/ && ./Host`
+
+  * 64bit emulator in Linux:
+
+    `cd Build/EmulatorX64/DEBUG_GCC5/X64/ && ./Host`
+
+**On posix-like environment with the bash shell you can use EmulatorPkg/build.sh to simplify building and running
+emulator.**
+
+For example, to build + run:
+
+`$ EmulatorPkg/build.sh`  
+`$ EmulatorPkg/build.sh run`
+
+The build architecture will match your host machine's architecture.
+
+On X64 host machines, you can build + run IA32 mode as well:
+
+`$ EmulatorPkg/build.sh -a IA32`  
+`$ EmulatorPkg/build.sh -a IA32 run`
