Provide warning in README or program, that exact path of CSV must be provided

[Riveascore]

Summary

If I try to run using a relative path ./a_text_exports/Default.csv, I get an error (posted at bottom).

I have to use the exact path:
/Users/USER/Downloads/alfred-snippets-master/a_text_exports/Default.csv

So it might be worth mentioning in the README, or just allow relative path inputs.

Full Error:

The project is stale since 7 years and I haven't used it since. If you think the comment would improve the README, I'm glad to merge a pull request!
