+# The Mover
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, your cargo bay is built. Now stock it.
+>
+> When your script runs, an `inbox/` of fresh supplies has arrived.
+> Each item is labeled by category — `food-`, `water-`, or `tool-`.
+> Sort them into the right rooms. Then make a backup of the food
+> manifest.
+>
+> Two commands:
+>
+> - `mv` — move (or rename)
+> - `cp` — copy
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+In `starter/starter.sh`, write the commands to:
+
+1. Move each `food-*` file into `cargo/food/`
+2. Move each `water-*` file into `cargo/water/`
+3. Move each `tool-*` file into `cargo/tools/`
+4. Copy `cargo/food/manifest.txt` to `cargo/food/manifest.backup`
+
+## Objectives
+
+- All `food-*`, `water-*`, `tool-*` files moved to the correct rooms
+- `cargo/food/manifest.backup` exists

+# When this script runs:
+#   - cargo/food/, cargo/water/, cargo/tools/ already exist
+#   - cargo/food/manifest.txt exists (empty)
+#   - inbox/ contains files with prefixes:
+#       food-apple.txt, food-bread.txt
+#       water-bottle.txt, water-canteen.txt
+#       tool-wrench.txt, tool-hammer.txt
+#
+# Your script must:
+#   1. Move all food-*.txt files into cargo/food/
+#   2. Move all water-*.txt files into cargo/water/
+#   3. Move all tool-*.txt files into cargo/tools/
+#   4. Copy cargo/food/manifest.txt to cargo/food/manifest.backup
