+# firstly, please reference https://edk2.tianocore.org/unix-getting-started.html to 
+# to get how to setup build tool.
+#
+# After build tool is downloaded and compiled, a soft symbol linker need to be created
+# at <workspace>/Conf. For example: ln -s /work/BaseTools /work/edk2/Conf/BaseToolsSource.

 # Setup the environment for unix-like systems running a bash-like shell.
 # This file must be "sourced" not merely executed. For example: ". edksetup.sh"

 # CYGWIN users: Your path and filename related environment variables should be
 # set up in the unix style.  This script will make the necessary conversions to
 # windows style.
