+To do this, write out your request prompt in a comment addressed to `@coderabbitai`,
+such as with the following examples:
 
-After you give it a code-generation command, CodeRabbit delivers its suggested improvements by taking these steps:
+- `@coderabbitai Please implement the changes you suggested in your code review.`
+- `@coderabbitai Add input validation with proper error messages to these new functions.`
+- `@coderabbitai Break this large function into smaller, more focused methods.`
 
+Beyond this kind of free-form request, you can also give CodeRabbit keyword-based
+commands for common code-generation requests, as described in [Code generation commands](#commands).
+This includes the `plan` keyword, which acts as shorthand for the first prompt on the
+previous list.
+
+After you give it a code-generation prompt or command, CodeRabbit delivers its suggested improvements by taking these steps:
+
+1. CodeRabbit posts a comment or two to the pull request, detailing its improvement plans.
 1. CodeRabbit publishes a new branch, based on the open pull request's branch, to the remote repository.
 1. CodeRabbit opens a new pull request based on this new branch, and links to it from the original pull request.
