const title = `# 1 on 1 Meeting Questions
Mega list compiled from a variety to sources. Also available here: http://www.managersclub.com/mega-list-of-1-on-1-meeting-questions/

I wrote a book about 1 on 1 meetings. You can find it here: https://www.amazon.com/Effective-One-Ones-Productive-Meaningful-ebook/dp/B0BY89ZZP4

## Applications using this data

Simple React app from @shershen08 that displays random questions from the list
https://compassionate-bose-f21503.netlify.app/
repo here: https://github.com/shershen08/react-tailwind-question-generator

Another app from @perlin, https://1on1questions.netlify.app/

const faq = `

## FAQ

Why is there also a JSON file?
- It can be directly consumed by apps
- README.md can be generated from json file so you only have to make changes in one place`;
const contributing = `
## Contributing
1. Fork repo
2. Add your question to \`questions.json\`.
3. Create new Pull Request

You can update the README manually running \`npm start\` but there is GitHub action that will automatically update the README with your questions.
