 ### Examples
  - Inspect a string:
    ```
-   java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -s "My phone number is (123) 456-7890 and my email address is [email protected]"

    ```
  - Inspect a local file (text / image):
    ```
-     java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -f resources/test.txt
-     java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -f resources/test.png

+     java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -f src/test/resources/test.png --infoTypes PHONE_NUMBER EMAIL_ADDRESS
    ```
 - Inspect a file on Google Cloud Storage:
   ```
-    java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -gcs -bucketName my-bucket -fileName my-file.txt
+    java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -gcs -bucketName my-bucket -fileName my-file.txt --infoTypes PHONE_NUMBER EMAIL_ADDRESS

 - Inspect a Google Cloud Datastore kind:
   ```
-    java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Inspect -ds -kind my-kind

 ### Example
-- Replace sensitive data in text with `_REDACTED_`:
+- Redact phone numbers and email addresses from `test.png`:
   ```
-    java -cp target/dlp-samples-1.0-jar-with-dependencies.jar com.example.dlp.Redact -s "My phone number is (123) 456-7890 and my email address is [email protected]" -r "_REDACTED_"
