-## Proxying
-Using the --proxy keyword makes everything faster because it creates some smaller files. 
-```
-gnommo -p myproject pre --proxy
-gnommo -p myproject stitch --proxy
-gnommo -p myproject render --proxy
-```
+## Resolution modes
 
-## Lowres
-Renders the final video in a low-res mode, for faster iteration
-```
-gnommo -p myproject render --res low
+All commands accept `--res` to trade quality for speed during iteration:
+
+| Flag | Resolution | Use case |
+|---|---|---|
+| `--res full` | Project resolution (default) | Final output |
+| `--res low` | 490×270 | Fast preview render |
+| `--res tiny` | 320×180 | Ultrafast iteration (preprocess, stitch, render) |
+
+`--res tiny` and `--res low` create downscaled copies of source files in subdirectories (`proxy/` and `low/` respectively) and work from those. The originals are never modified.
+
+```bash
+gnommo -p myproject pre --res tiny       # fast preprocess
+gnommo -p myproject stitch --res tiny    # fast stitch
+gnommo -p myproject render --res tiny    # fast preview render
+gnommo -p myproject render --res low     # medium preview render
