+# Rendering markdown to PDF
+
+For documents I intend to distribute (such as this CV), I typically watch markdown files for changes in a couple tmux panes, rendering them to PDF. If the resulting CV is a bit staid, it makes up for it with version control on the CV's contents, and a good workflow. I haven't really automated it beyond this yet.
+
+## Prerequisites
+
+- Pandoc (https://github.com/jgm/pandoc)
+- A CSS file used by Pandoc for rendering the PDF, in this case something approximating GitHub's readme style (https://github.com/sindresorhus/github-markdown-css, or some such)
+- entr (https://github.com/eradman/entr), or some inotify-compatible alternative
+
+## Command
+```bash
+echo README.md | entr -s 'pandoc -f gfm -t html --metadata pagetitle="CV, Nicholas Warzin, 2023" --css github.css README.md -o cv_nicholas-warzin_2023.pdf''
+```
+### Explanation
+
+- `-f gfm` Assume README.md is written in GitHub-flavoured Markdown, ensuring consistent rendering as a PDF and as a repository's README.md
+- `-t html` Convert to PDF using HTML as the intermediate format (versus, say, LaTeX)
+- `--metadata pagetitle="..."` Give the document a readable page title
+- `--css github.css` Render the document like a GitHub readme
