 Censoring Logs
 ----------------
 
-Pod logs gathered by Robusta can be censored using regexes. For example, a payment processing pod might have credit card numbers in its log. These can be sanitized in-cluster.
+Pod logs gathered by Robusta can be censored using `Python regular expressions <https://www.w3schools.com/python/python_regex.asp>`_. For example, a payment processing pod might have credit card numbers or other sensitive information in its logs. These can be automatically sanitized before they appear in notifications.
 
-This feature applies to the following Robusta actions:
+**How to Enable Log Censoring for All Logs**
 
-- :code:`logs_enricher`
-- :code:`report_crash_loop`
+To censor sensitive information in all logs, add the following to your Helm values file:
 
-To censor logs, define a `python regex <https://www.w3schools.com/python/python_regex.asp>`_ for expressions you wish to filter.
+.. code-block:: yaml
 
-For example:
+    globalConfig:
+      regex_replacement_style: SAME_LENGTH_ASTERISKS  # Alternative: NAMED
+      regex_replacer_patterns:
+        - name: CreditCard
+          regex: "[0-9]{4}[- ][0-9]{4}[- ][0-9]{4}[- ][0-9]{4}"
+        - name: Email
+          regex: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}"
+        - name: UUID
+          regex: "[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"
 
-.. code-block:: yaml
+After adding these values, perform a Helm upgrade:
+
+.. code-block:: bash
 
-    - logs_enricher:
-        regex_replacement_style: SAME_LENGTH_ASTERISKS # You can also use NAMED
-        regex_replacer_patterns:
-          - name: MySecretPort
-              regex: "my secret port \\d+"
-          - name: UUID
-              regex: "[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"
+    helm upgrade robusta robusta/robusta -f values.yaml
 
-Given the following input:
+**Example: Before and After Censoring**

+**Note:** This censoring applies to logs displayed in Robusta's built-in notifications, including those shown by the following Robusta actions:
 
-    globalConfig: # Note: no need to specify logs_enricher or report_crash_loop by name here.
-      regex_replacement_style: SAME_LENGTH_ASTERISKS
-      regex_replacer_patterns:
-        - name: MySecretPort

-        - name: UUID

+- :code:`logs_enricher` - Shows container logs in various alerts
+- :code:`report_crash_loop` - Shows container logs for crashing pods
 
-Place these values inside Robusta's Helm values and perform a :ref:`Helm Upgrade <Simple Upgrade>`.
+For specific actions, you can also override these settings in your playbook definitions if needed.
