 ## Getting Started
 
+To enable Sentry Prevent AI in your GitHub organization or on specific repositories, you need to install the [Seer by Sentry app](https://github.com/apps/seer-by-sentry). This allows the assistant to analyze pull requests, provide insights, and write tests. **You must also have the [Sentry Github integration](/organization/integrations/source-code-mgmt/github/) enabled.**
+
 1. Install the [Seer by Sentry app](https://github.com/apps/seer-by-sentry) in your GitHub organization or specific repositories.
 2. Enable these required settings in your Sentry [organization settings](https://sentry.io/orgredirect/settings/:orgslug/):
    - `Show Generative AI Features`
    - `Enable PR Review and Test Generation`
 
-If you're not an admin, share the Sentry Prevent AI GitHub App Integration link with your organization's admin or owner to install.

 ## Sentry Prevent AI Commands
 
-After installing the app, use these commands in your pull request comments:
+After installing the app, Sentry Prevent AI can help you in three ways:
+
+1. **Error Prediction** - When you create a pull request and set it to `Ready for Review`, Sentry Prevent AI will check for errors in your code. If no error is found, you will see a 🎉 emoji as a reaction to your PR description. Otherwise, Sentry Prevent AI will add comments to your PR. 
 
-- `@sentry review` - The assistant will review the PR and make suggestions.
+2. **`@sentry review`** - Use this command in a PR comment, and the assistant will review the PR and predict errors, as well as make suggestions.
 
-- `@sentry generate-test` - The assistant will generate tests for your PR.
+3. **`@sentry generate-test`** - Use this command in a PR comment, and the assistant will generate tests for your PR.
 
 Once you have added a comment, the assistant will reply, acknowledging the request. For code reviews, you will then see comments added to your PR. For test generation, you will see a comment with a link to the generated tests.
