Creating a DVC pipeline

Imagine a simple example of a workflow where a document is printed and then scanned to create a signed PDF document, with DVC managing the dependencies and outputs of each stage.

The print stage depends on printing instructions outlined in print.sh and produces the pages output. The scan stage depends on instructions in scan.sh and pages (output of printer) and produces a signed.pdf output.

Your task is to design a DVC pipeline outlining the workflow using the dvc stage add command. Its syntax is

dvc stage add -n <stage_name> -d <dependency> -o <output> <command>

You can add multiple dependencies and outputs with repeated use of -d and -o flags, respectively.

NOTE: DVC has already been initialized in the exercise setup. There is no need to run dvc init again.
