 Step 1: Install dependencies
 ****************************
 
+.. note::
+    Right now, debian stable ships with a rust that is so stable it can't even build half of usvg's dependencies. That's
+    why we yolo-install our own rust here. Sorry about that. I guess it'll work with the packaged rust on sid.
