Thank you for your project. The idea of CV generation out of structured config file seems much more elegant rather then using online builders where you need to focus on formatting. Thanks for LaTeX formatting.
I faced the following issue when file could not be rendered with following format of phone number:

cv:
  name: John Doe
  headline: Machine Learning Engineer
  location: San Francisco, CA
  email: john@example.com 
  phone: +14155551234

It looks like validation relies on Pydantic and validation fails because it expects string but receives integer number instead. Validation succeeds if number is enclosed in quotes:

 cv:
  name: John Doe
  headline: Machine Learning Engineer
  location: San Francisco, CA
  email: john@example.com 
  phone: "+14155551234"

I'm suggesting to update the documentation.
Also, country prefix is removed from rendered output. But there are cases where user is located in one country while phone number is issued by other country. Please consider adding country prefix to avoid confusions with contact details.
