+# copilot.lua within CMP
+
+Fully featured & enhanced replacement for copilot.vim complete with API for interacting with Github Copilot
+
+**Repositories:** 
+<https://github.com/zbirenbaum/copilot.lua>
+<https://github.com/zbirenbaum/copilot-cmp>
+
+_Note_: This plugin will also reconfigure `cmp` and add `copilot` as a completion source
+_Note 2_: This configuration adds a nerdfont icon for copilot using `lspkind`. If you are using regular characters, you can change it in your plugin setup, using the key `Copilot` for `lspkind`'s `buffer_map`
