 ### Test your content exclusions
 
-There are a few different ways to test your content exclusions, depending on which IDE you're using.
+You can verify that content exclusions you have configured are working as expected.
+
+1. First confirm that content exclusion is working in files that are not subject to content exclusion. To do this:
+   * In your IDE, open a file that is not subject to content exclusion.
+   * Make an edit that would normally generate a code completion suggestion. A suggestion should be offered
+1. Open a file that should be excluded and make the same edit. No suggestion should be offered.
+1. To test content exclusion for {% data variables.copilot.copilot_chat_short %}:
+   * In your IDE, open the {% data variables.copilot.copilot_chat_short %} panel.
+   * Open a file that should be excluded and close any other files that are open in the editor.
+   * Make sure that the open file is attached to the prompt as the context file.
+   * Enter the prompt `explain this file`.
 
-1. Open a file that you expect to be affected by your content exclusions.
-1. Use one or more of the following techniques to test if content is being excluded:
-   * **In JetBrains IDEs, {% data variables.product.prodname_vs %}, and {% data variables.product.prodname_vscode %}**, check the {% data variables.product.prodname_copilot_short %} icon in the status bar. If a {% data variables.product.prodname_copilot_short %} content exclusion applies to the file, the {% data variables.product.prodname_copilot_short %} icon will have a diagonal line through it. Hover over the icon to see whether an organization or the parent repository disabled {% data variables.product.prodname_copilot_short %} for the file.
-   * **In Vim/Neovim**, begin typing in the file. If {% data variables.product.prodname_copilot %} no longer provides inline suggestions as you type, the file is excluded.
-   * You can also test content exclusions in {% data variables.copilot.copilot_chat_short %}. Open the {% data variables.copilot.copilot_chat_short %} window, and ask {% data variables.copilot.copilot_chat_short %} a question about the excluded file. If your content is excluded successfully, {% data variables.product.prodname_copilot_short %} will be unable to answer your question, and will explain that some files were excluded from the conversation due to content exclusion rules.
+     If the file is excluded, {% data variables.copilot.copilot_chat_short %} will not be able to use the file to generate a response. The file will not be listed as a reference in {% data variables.product.prodname_copilot_short %}'s response.
