+# The Maker
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, you've walked the field. Now build something.
+>
+> When your script runs, a stale file `cargo-old.txt` is sitting in
+> your working directory. Build a cargo bay with three rooms — `food/`,
+> `water/`, `tools/` — each holding an empty `manifest.txt`. Then
+> delete the stale file.
+>
+> Three commands:
+>
+> - `mkdir` — make a directory (use `-p` to make nested ones at once)
+> - `touch` — create an empty file
+> - `rm` — delete (be careful — there is no trash)
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+In `starter/starter.sh`, write the commands to:
+
+1. Create `cargo/food/`, `cargo/water/`, `cargo/tools/`
+2. Create an empty `manifest.txt` in each room
+3. Remove `cargo-old.txt`
+
+## Objectives
+
+- All three room directories exist
+- Each contains an empty `manifest.txt`
+- `cargo-old.txt` no longer exists
