I would rather want to restart my module 3 again from scratch

I have worked on module 3 and coz of some family things am unable to work on the project for 3 days and now i am not clear where i has stopped!
Please help me restart my module 3!

Module 3 is basically configuring the Vsftpd config file, you can continue the task from module 3 and understand as to what type of boolean options can be used to configure a Vsftpd server
