# Thanks for contributing! ## Before adding issues Please verify the problem is actually a snappy problem and not a **wkhtmltopdf problem**. To do so, simply copy paste the command displayed in the error message in your command prompt. If the same error appears on the command line, then it's a wkhtmltopdf problem, and you'll have more chance to resolve your issue [there](https://github.com/wkhtmltopdf/wkhtmltopdf/issues).
