+# The Prompt
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, every program takes input. In this stage, your functions
+> receive input as *parameters* — values passed in by whoever called
+> you.
+>
+> *f-strings* (formatted strings) embed values directly into text:
+>
+> ```python
+> name = "Vega"
+> f"Hello, {name}!"   # → "Hello, Vega!"
+> ```
+>
+> Implement `welcome(name, planet)` that returns:
+>
+> ```
+> Welcome, <name> from <planet>.
+> ```
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+Open `starter/starter.py`. Use an f-string to return the welcome
+message.
+
+## Objectives
+
+- `welcome("Vega", "Mars")` → `"Welcome, Vega from Mars."`
+- Works for any name and planet
