+## How it works
+
+The question generator uses a simple branching structure inside the specified locale to generate questions from it, here is a quick example:
+
+```yml
+Can:
+  you:
+    - swim
+    - speak:
+      - different:
+        - languages
+    - play:
+      - any:
+        - sports
+      - the:
+        - piano
+        - guitar
+        - trumpet
+      - baseball
+    - ski
+    - cook
+    - dance
+
+# The following example outputs:
+# Can you swim?
+# Can you speak different languages?
+# Can you play any sports?
+# Can you play the piano?
+#               ...guitar?
+#               ...trumpet?
+# Can you play baseball?
+# Can you ski?
+# Can you cook?
+# Can you dance?
+```
+
+If you can't break sentences in parts in your language, you can also specify the entire question in one line.
+```yml
+- Can you swim?
+
+# The following example outputs:
+# Can you swim?
+```
