+## Smart Apply code suggestions
+
+Cody lets you dynamically insert code from chat into your files with **Smart Apply**. Every time Cody provides you with a code suggestion, you can click the **Apply** button. Cody will then analyze your open code file, find where that relevant code should live, and add a diff. For chat messages where Cody provides multiple code suggestions, you can apply each in sequence to go from chat suggestions to written code.
+
+Smart Apply also supports executing commands in the terminal. When you ask Cody a question related to terminal commands, you can execute the suggestion in your terminal by clicking the `Execute` button in the chat window.
