+BaseTools Simple Usage:\r
+1) Change the directory to the EDK2 root directory, where the edksetup.bat is\r
+2) Run "edksetup.bat NewBuild"\r
+3) Set the ACTIVE_PLATFORM to your desired platform description file \r
+   (%WORKSPACE%\Conf\target.txt)\r
+4) To build platform, run "build" command in non-module directory\r
+5) To build module individually, run "build" command in module directory, i.e. where the \r
+   *.inf file is\r
+\r
+Notes:\r
+1) Only *.efi files can be generated. Flash image cannot be generated at present.\r
+2) Only "clean" and "cleanall" build target are supported, in both top level \r
+   makefile and module's makefile. \r
+3) Not all tool chains and target architectures are tested. Due to both tools \r
+   and source code limitations, ther must be bugs in it. Please report any issue \r
+        ASAP so we can fix it soon.\r
+4) The tree structure generated by build tools is similar to Ant build system.\r
+5) Makefile can be called directly by nmake for both top level platform and module. But\r
+   after you call "nmake cleanall", you have to call "build" command to rebuild platform\r
+        or modules because the AutoGen.* files have been be removed. The "makefile" itself\r
+        cannot generate AutoGen.* files. Only "build" command can.\r
