Can you say what you tried, and what didn't work? You don't need github:
the parmed program is a part of AmberTools. Type "parmed" on the command
line, then "help" at the prompt, followed by "help <command>" for help on
specific commands. Section 15.2 in the Manual has more detailed
explanations, and section 15.2.3 has a number of commented examples. I hope
these will help.
