+# ranger
+
+This directory tracks the ranger setup I actually use instead of storing a
+full copy of the packaged defaults.
+
+## Files
+
+- `rc.conf`: minimal overrides on top of ranger's built-in defaults
+- `scope.sh`: richer previews for images, video, PDF, archives, and text
+
+## Recommended packages on Arch Linux
+
+```bash
+sudo pacman -S --needed \
+  ranger ueberzugpp chafa ffmpegthumbnailer mediainfo highlight atool \
+  perl-image-exiftool w3m mpv trash-cli unrar poppler imagemagick bat jq file
+```
+
+## Notes
+
+- `preview_images_method ueberzug` works well in X11 terminals such as Alacritty.
+- `chafa` provides a readable fallback when graphical image previews are unavailable.
+- `trash-cli` powers the `dt` and `dT` key bindings in `rc.conf`.
