 The app can provide real-time code suggestions based on the files you have opened. It's powered by GitHub Copilot and Codeium.
 
+The feature provides two presentation modes:
+- Nearby Text Cursor: This mode shows suggestions based on the position of the text cursor.
+- Floating Widget: This mode shows suggestions next to the circular widget.
+
+When using the "Nearby Text Cursor" mode, it is recommended to set the real-time suggestion debounce to 0.1.

 If you're working on a company project and don't want the suggestion feature to be triggered, you can globally disable it and choose to enable it only for specific projects.
 
 Whenever your code is updated, the app will automatically fetch suggestions for you, you can cancel this by pressing **Escape**.

-## Prevent Suggestions Being Committed (in comment mode)
-
-Since the suggestions are presented as comments, they are in your code. If you are not careful enough, they can be committed to your git repo. To avoid that, I would recommend adding a pre-commit git hook to prevent this from happening.
-
-```sh
-#!/bin/sh
-
-# Check if the commit message contains the string
-if git diff --cached --diff-filter=ACMR | grep -q "/*========== Copilot Suggestion"; then
-  echo "Error: Commit contains Copilot suggestions generated by Copilot for Xcode."
-  exit 1
-fi
-```

 ## Limitations
 
-- The first run of the extension will be slow. Be patient.
 - The extension uses some dirty tricks to get the file and project/workspace paths. It may fail, it may be incorrect, especially when you have multiple Xcode windows running, and maybe even worse when they are in different displays. I am not sure about that though.
-- The suggestions are presented as C-style comments in comment mode, they may break your code if you are editing a JSON file or something.
