Thanks, @si-net! Could you please run Prettier on the README? It's failing the format-check step.

I'm actually exploring PDF support in main...add-pdf-format-support, but for now the FAQ will be helpful.

I ran prettier locally, no errors

I tired to add the --write option to your pipeline, so you actually see what it complains about, but I could not find the correct place to add it, Its not an explicit stage in your actions, and seems to be part of the npm built process.

Good to know that you are working on pdf support, thank you!

In the meantime I think the way to go is to actually use json-resume themes, that are built with pdf-support in mind.

Many of the themes out there will just never fit on one page, so even when exporting them, you don't gain much. Seems to me like the way to go is with changing the themes so that they are ready for pdf.

You can run npm run format -- --write to format all files. Looks like there's a trailing space at the end of a heading and an extra line at the bottom of the file.
