+# The Greeting
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, your first Python. Implement a function called `greet` that
+> returns the exact string:
+>
+> ```
+> Hello, Python
+> ```
+>
+> Two pieces of syntax:
+>
+> - `def name():` defines a function
+> - `return value` sends a value back to whoever called it
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+Open `starter/starter.py`. Replace `pass` with a `return` statement
+that returns `"Hello, Python"`.
+
+## Objectives
+
+- A function `greet` exists
+- `greet()` returns `"Hello, Python"`
