+## flags
+
+### Instructions
+
+Write a **program** that can have as arguments `--insert` (or `-i`),  `--order` (or `-o`) and a `string`.
+
+This program should :
+
+- Insert the string given to the `--insert` (or `-i`), in the `string` argument, if given.
+- Order the `string` argument if given the flag `--order` (or `-o`).
+- In case there are no arguments or the flag `--help` (or `-h`) is given, it should print the options, as shown in the example.
+
+Example of output :
+
+```console
+student@ubuntu:~/piscine-go/flags$ go build
+student@ubuntu:~/piscine-go/flags$ ./flags --insert=4321 --order asdad
+1234aadds
+student@ubuntu:~/piscine-go/flags$ ./flags --insert=4321 asdad

+student@ubuntu:~/piscine-go/flags$ ./flags --order 43a21
+1234a
+student@ubuntu:~/piscine-go/flags$ ./flags
+--insert
+  -i
+    This flag inserts the string into the string passed as argument.
+--order
+  -o
+    This flag will behave like a boolean, if its called it will order the argument.
+student@ubuntu:~/piscine-go/flags$
+student@ubuntu:~/piscine-go/flags$ ./flags -h
+--insert
+  -i
+    This flag inserts the string into the string passed as argument.
+--order
+  -o
+    This flag will behave like a boolean, if its called it will order the argument.
+student@ubuntu:~/piscine-go/flags$
+student@ubuntu:~/piscine-go/flags$ ./flags --help
+--insert
+  -i
+    This flag inserts the string into the string passed as argument.
+--order
+  -o
+    This flag will behave like a boolean, if its called it will order the argument.
