Can you give more details of how to run the application?

Hi. Can you give more details on how to run the application? README.md seems too scarce on information.
I tried **go run license_serializer.go**. It works fine.
But **identify_license** can't find **licenses.db**.
I have an error **2023/03/29 20:33:49 cannot create license classifier: cannot register licenses from archive: open licenses.db: file does not exist**.
Where does **licenses.db** need to be located ?

Another question - how does it scan the files?
I have all licenses files (*.txt) in one folder. Do I need to indicate the path on this?
Does it also work on a folder recursively?

Please add more details in README.md. Thank you.
