@@ -4,6 +4,27 @@ A Rust library for displaying dialog boxes using various backends.
 
 [Documentation][]
 
+Currently `dialog-rs` supports input, message, password and question dialogs.
+It can use the `dialog` or `zenity` tools to display the dialog boxes.  If none
+of these tools is available, the dialogs are printed to the standard output.
+
+## Example
+
+```rust
+use dialog::DialogBox;
+
+let choice = dialog::Question::new("Would you like to install Rust?")
+    .title("Rust Installation")
+    .show()
+    .expect("Could not display dialog box");
+if choice == dialog::Choice::Yes {
+    dialog::Message::new("You made the right choice!")
+        .title("Rust Installation")
+        .show()
+        .expect("Could not display dialog box");
+}
+```
