+### FTP Assignment Submission
+
+
+### How to operate
+- There are some issues in my code  . I have to fix them.
+- I have made the necessary function that was given in the assignment.
+- Firstly joining of client . Client will be asked whether he is new or not.
+- Then if Server wants to adduser then he or she can type ADDUSER command.
+- There are four commands.
+   - STORE
+   - RETRIEVE
+   - QUIT
+   - LIST
