@@ -463,6 +464,13 @@ Note that we face some issues about the use of _Gitleaks GitHub Action_ and _Git
 
 Remember _Gitleaks_ is also used in GitHub project side thanks to the [dedicated GitHub Action](https://github.com/marketplace/actions/gitleaks) but these controls are done online once commits have left the local environment.
 
+## Linter
+
+We use _SwiftLint_ in this project so as to be sure the source code follows defined guidelines for the syntax and other points.
+You must run _SwiftLint_ in CLI or using _Xcode_ to be sure you don't keep and submit warnings.
+In most of cases you **must** fiw warnigns, but it could happen some of them should be disabled, mainly for tests cases.
+Explain why in yout commtis and pull request comments you choose to disable them.
+
 ## CI/CD
 
 We use GitLab CI for CI/CD with our own runners so as to keep private our sensitive files likes certificates and provisioning profiles.
