 # QuickArgParse
 Fast command line argument parsing in Julia. No bells and whistles.
+
+### Example
+All inputs except req are optional.  
+
+```Julia
+req = ["Arg1","Arg2"]
+reqhelp = ["First Argument","Second Argument"]
+opts= ["opt1","opt2"]
+optsHelp = ["First optional argument","Second optional argument"]
+optsDefault = ["opt1 default","opt2 default"]
+flags = ["w"]
+flagHelp = ["a flag, true/false (default false)"]
+title = "Example usage statement"
+desc = "A demo version of a usage statement showing the code required to generate it"
+
+
+R = process_reqs(req;reqHelp=reqhelp,flags=flags,flagHelp=flagHelp,title=title,desc=desc,
+	optTag=opts,optHelp=optsHelp,optDefault=optsDefault)
+build_usage!(R)
+A = parse_args(R)
+```
