 These instructions are also meant for problematic cases where you want to modify the rules that are bundled with the extension statically. In most cases, using *User rules* in the extension should be sufficient.
 
+Additionally, you can edit filters and rebuild DNR rulesets without rebuilding the entire extension, which may be useful for debugging purposes.

+##### How to debug rules
 
-1. Find and modify the rule you need in the `./Extension/filters/chromium-mv3` directory in the `.txt` files.
+You can debug and update DNR rulesets without rebuilding the entire extension. There are two main workflows:
 
-1. Convert the rules from txt to declarative form:
+**A. Automatic (recommended for most cases):**
 
-    ```bash
-    yarn convert-declarative
+1. **Build the extension** (if not done yet):
+    ```shell
+    pnpm install
+    pnpm dev chrome-mv3
+    ```
+
+1. **Start watching for filter changes:**
+    ```shell
+    pnpm debug-filters:watch
     ```
+    - This will extract text filters to `./build/dev/chrome-mv3/filters` and watch for changes.
+    - When you edit and save any filter file, DNR rulesets will be rebuilt automatically.
 
-1. Build the extension again:
+1. **Reload the extension in your browser** to apply new rulesets.
 
-    ```bash
-    yarn dev chrome-mv3
+**B. Manual (for advanced/manual control):**
+
+1. **Build the extension** (if not done yet):
+    ```shell
+    pnpm install
+    pnpm dev chrome-mv3
+    ```
+
+1. **Extract text filters:**
+    ```shell
+    pnpm debug-filters:extract
+    ```
+
+1. **Edit the text filters** in `./build/dev/chrome-mv3/filters` as needed.
+
+1. **Convert filters to DNR rulesets:**
+    ```shell
+    pnpm debug-filters:convert
+    ```
+
+1. **Reload the extension in your browser** to apply new rulesets.
+
+**Tip:**
+- To download the latest available text filters, run:
+    ```shell
+    pnpm debug-filters:load
     ```
 
-1. Reload the extension in the browser:
+If you see an exclamation mark in the filtering log, it means the assumed rule (calculated by the engine) and the applied rule (converted to DNR) are different. Otherwise, only the applied rule (in DNR and text ways) will be shown.
