title: Gatsby + Markdown: How to get data from a specific markdown file into a single page?
body: <p>I'm new to Gatsby, and making my best to learn it (along with React, in which I have no prior knowledge either). I'd like to create a single page getting data from one or several markdown files.</p>
  
  <p>For now I'm testing it out with just Gatsby, in order to later reproduce that technique with Netlify CMS markdown files (and be able to update the page texts with Netlify CMS admin panel).
  So far, I've managed to add markdown pages to Gatsby, thanks to this <a href="https://www.gatsbyjs.org/docs/adding-markdown-pages/" rel="noreferrer">tutorial</a>. But this method only creates dynamic pages, which is far more complex than what I need.</p>
  
  <p>Is there a simple way to import one specific markdown file, let's say src/markdowns/hero-texts.md, in (let's also say) pages/index.js, and then call data with their frontmatter tags, in the cleanest way as possible?</p>
  
  <p>I've tried countless researches on Google just to find which plugin or coding term would handle that, without success. I totally get some of the explanations above may be full of technical misunderstandings, sorry for that...</p>
