 Usage: fcidr [CIDR] <COMMAND>
 
 Commands:
-  complement  Compute the complement of the input CIDR(s)
-  difference  Compute the set difference between the input CIDR(s) and another CIDR [aliases: exclude, minus]
-  union       Compute the set union of the input CIDR(s) and another CIDR [aliases: include, plus]
+  complement  Compute the complement of the input CIDR(s) [aliases: !, not]
+  difference  Compute the set difference between the input CIDR(s) and another CIDR [aliases: -, exclude, minus]
+  union       Compute the set union of the input CIDR(s) and another CIDR [aliases: +, include, plus]
   help        Print this message or the help of the given subcommand(s)
 
 Arguments:
   [CIDR]  The input CIDR range and first operand to the computation. If omitted, input is taken from stdin. In this way, multiple computations can be chained together
 
 Options:
   -h, --help     Print help
-  -V, --version  Print version
+  -V, --version  Print version`
 ```
