-To chat with Copilot, follow these steps:
+You can customize the CopilotChat plugin using the following configuration options:
+
+```lua
+{
+  debug = false, -- Enable or disable debug mode

+    Explain = 'Explain how it works.',
+    Tests = 'Briefly explain how the selected code works, then generate unit tests.',
