+
+## FAQ
+
+### Why?
+
+To keep your non-tech significant other happy. The terminal can be a dark place for some people.
+
+### Why do you use OCRmyPDF version 12.7.2?
+It is the last version which supports remove background. Which is somewhat impossible to find in normal PDF editors. Otherwise, OCRmyPDF works flawlessly, and I yet haven't found an issue which makes me want to upgrade.
