+# Verse
+
+**Verse is an online programming tool** that makes it easy to
+create simple programs and games. In the future, you'll
+be able to share your programs and remix others' work, too.
+
+**Verse is designed with beginners in mind.** It's a great way
+to start learning to code. But even professional programmers
+will find it useful for quickly sketching ideas or bringing
+their side projects to life.
+
+[**Try it out!**](https://druidic.github.io) No need to create
+an account or log in. Just click the link and start coding.
+Here's a simple program you can copy-paste to get started.
+
+```javascript
+define({
+    *init() {
+        let intro = "Hello! What's your name?"
+        let name = yield waitForInput(intro)
+        yield log('Nice to meet you, ' + name + '!')
+        yield wait(1)
+        yield retry()
+    }
+})
+```
+
+Once you're ready for more, you can continue reading the
+Verse documentation here... but first, tell us a bit about
+your programming experience.
