# Customizing Quality Profiles ### Overview **Quality Profiles** determine the list of rules used in a scan. Quality Profiles can be customized by adding and removing rules, setting severities, and changing scope where applicable. To make a custom Quality Profile, you can create a new profile or copy one of our default profiles from the list as a starting point. {% hint style="info" %} **Note:** Changes **CANNOT** be made to default profiles, only to custom profiles. If you are using a default profile and would like to remove a rule, please make a copy of the default profile and make your changes to the copied profile. {% endhint %} ### Creating a Quality Profile To customize the Quality Profile, follow the steps below: 1. Access the Quality Profile menu from the Organization’s home page.

2. Use the **Create** button at the top right of the page to create a new Quality Profile.

3. Enter the **Name** and choose a **Language** for the profile. Additionally, you can either extend/copy an existing Quality Profile or create a blank Quality Profile..

4. Click **Create**.

5. Click on the more icon and then click on **Copy** to copy a default profile.

6. Once you have chosen a name for your profile, click the **Activate More** button to begin your customization.

7. Use the filters on the left to determine the rules you want to see, and click the **Activate/Deactivate** button to add/remove them from your quality profile.

8. You can bulk activate/deactivate rules for your profile using the **Bulk Change** button.

9. When activating a rule, you will be given the option to change its **severity** and any other parameters the rule may have.

> **Example**:\ > You can update the severity of the rule to `Major/Critical/Minor/Blocker/Info` > > ![](https://1912836914-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F9vAxMuDrkUkB4OXlH9CL%2Fuploads%2FL2Tav7ytrah3PE9mEjoi%2FSeverity%20List%209.3.png?alt=media\&token=c55a17f0-16d7-4c57-a779-fd3634baff74) > > To use the rule mentioned above, the parameter `minimumCommentDensity` needs to be set to a value. The minimum value is 25. If you use the value of 35 as an example, the density of comment lines of 35 will be considered. > > Set the value for `suppressUnitTestViolations`.\ > `Default`: *The Default is actually 'Display' and it will display the unit test violations suppression, means, the issues will get displayed in Test Classes for the parameters.*\ > `Display`: *Displays the unit test violations suppression.*\ > `Suppress`: *Unit test violations will be suppressed.*
