-* **Customize size**: If you want to control the length and the error-correction-level, use the `-v` and `-l` arguments. The `-v`  representing the length is from 1 to 40 that 1 means minimum and 40 means maximum. The `-l`  representing the level is one of L, M, Q and H that L means lowest and H means highest.
