   def caveats
     <<~EOS
-      Default config files are stored in:
-        #{etc}/cheatsh/
- 
-      To set up your config on first run:
-        cp #{etc}/cheatsh/commands_template.json ~/.config/cheatsh/
+      cheatsh uses the bundled command list by default (updated on `brew upgrade`):
+        #{opt_pkgshare}/commands.json
+
+      To use your own list, copy the template and pass it explicitly:
+        cp #{opt_pkgshare}/commands_template.json ~/my-commands.json
+        cheatsh --config ~/my-commands.json
+
+      Copying to the clipboard needs a backend on Linux:
+        wl-clipboard (Wayland) or xsel / xclip (X11). macOS works out of the box.
