+# Design document
+
+The GC pacer design document is generated from the `.src.md` file in this
+directory.
+It contains LaTeX formulas which Markdown cannot render, so they're
+rendered by an external open-source tool,
+[md-latex](https://github.com/mknyszek/md-tools).
+
+Then, because Gitiles' markdown viewer can't render SVGs, run
+
+```
+./svg2png.bash
+cd pacer-plots
+./svg2png.bash
+cd ..
+```
+
+And go back and replace all instances of SVG with PNG in the final document.
+
+Note that `svg2png.bash` requires both ImageMagick and Google Chrome.
