 Refer to the default [gitleaks config](https://github.com/zricethezav/gitleaks/blob/master/config/gitleaks.toml) for examples or follow the [contributing guidelines](https://github.com/zricethezav/gitleaks/blob/master/README.md).
 
+### Additional Configuration
+If you are knowingly committing a test secret that gitleaks will catch you can add a `gitleaks:allow` comment to that line which will instruct gitleaks
+to ignore that secret. Ex:
+```
+class CustomClass:
+    discord_client_secret = '8dyfuiRyq=vVc3RRr_edRk-fK__JItpZ'  #gitleaks:allow
+
+```
