+// 1. Thank you for volunteering to document our pumpkin library! Let's start by grabbing the first
+// paragraph from https://en.wikipedia.org/wiki/Pumpkin and pasting it as our module-level
+// documentation. Hint: Use inner-documentation comments.
+//
+// Once you've got the documentation here, run `cargo doc --no-deps --open` and take a look!
+
+// 2. What about an image!? Add an image of a pumpkin to the end of the module-level documentation.
+// The markdown format is ![some alt text](https://url-to-the-image.png)
+// Here's the image to link to: https://upload.wikimedia.org/wikipedia/commons/thumb/5/5c/FrenchMarketPumpkinsB.jpg/700px-FrenchMarketPumpkinsB.jpg
+
+// 3. Document the Pumpkin struct.
+// - The description on the index page should be "Big orange thing"
+// - Make a section header called "Recipes"
+// - Explain that recipes will be coming soon.
+// - Explain that "roundness" is a percentage
+// - Explain that "orangeness" is a number from 8 to 27
+
+pub struct Pumpkin {
+    pub roundness: f32,
