We write software to improve our lives and the lives of others. Usually this involves taking some mundane information - such as contacts, invoices, or receipts - and manipulating it using a computer application.
The contacts word doesn't match a context here. It seems that you mistyped r.
Hoping to help out with a pull request, I checked into this issue :)
I think "contacts" (no "r") is what was intended and makes sense after reading through the rest of the section --
If everyone agrees, perhaps we can leave it as-is and close the issue?
