+# Silly Oak Intro Example
+
+Hooks Oak's NEW GAME speech: extra questions, sprite swaps (Oak, rival,
+player, MEW, and a custom Toast Kid pic), and answers stored in `mod.save`.
+
+## Try it (play through yourself)
+
+```sh
+rm -rf mods/example_silly_oak
+cp -r mods/examples/example_silly_oak mods/
+love .
+```
+
+Then **NEW GAME** and mash A / pick the menus. Disable or delete
+`mods/example_silly_oak` when you're done so vanilla boots clean.
+
+## Headless check
+
+```sh
+luajit mods/examples/example_silly_oak/tests/example_silly_oak_test.lua
