How to apply rules in SonarQube

Thank you for your tips. However, no matter how much I search and look through the documentation, I cannot find the process for applying the rules in SonarQube. I need a very detailed explanation. Can you provide it?

Hi @kss44kss,

In Sonarque, rules are managed through Quality Profile. Each language has a default quality profile (BUILT-IN). You can create your quality profile to activate/deactivate rules, modify severities or change parameters for the configured rules.
You can also develop your own rules, quality profile…
At the project level you can choose the quality profile to apply to each language detected.
