+# First Repo
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadets, your first paired exercise. One of you will set up a fresh
+> Git project; the other will verify it. Then swap.
+>
+> Pair up. Decide who goes first as **defender** and who goes first
+> as **attacker**.
+>
+> [END TRANSMISSION]
+
+## The Task
+
+The **defender** writes a single shell script — `setup.sh` — that,
+when run inside an empty workspace:
+
+1. Initializes a fresh Git repo on branch `main`.
+2. Sets `user.name` and `user.email` on the repo.
+3. Creates a file called `hello-world.txt` containing exactly:
+   ```
+   Hello, World
+   ```
+4. Stages and commits it with the message `add hello-world`.
+
+## Battle Rules
+
+- **Defender**: writes `setup.sh` in a clean workspace. Does not show
+  the file until done.
+- **Attacker**: receives the script, runs it in a clean folder,
+  inspects the resulting repo, and submits a review.
+- **Then swap**: roles flip; the new defender writes their own
+  `setup.sh` (no copy-pasting).
+- Both pass the battle if both scripts pass review.
+
+## Tools
+
+`git init`, `git config`, `echo`, `>`, `git add`, `git commit -m`.
