 ### Standalone NuGet
 
-Standalone NuGet packages can be configured the same way as SonarLint in connected mode. You can use SonarLint and SonarCloud to generate the ruleset and rule configuration file SonarLint.xml as described above and embed them into your project.
-
-You can see how we do it in our own repository for SonarLint Connected mode (and you can reuse the same concept for the NuGet package):
-
-* We reference in each production-code project this [Directory.Build.targets](analyzers/src/Directory.Build.targets).
-* This file points to the following ruleset: [sonaranalyzer-dotnetCSharp.ruleset](analyzers/.sonarlint/sonaranalyzer-dotnetCSharp.ruleset).
-* And the following [SonarLint.xml](analyzers/.sonarlint/sonaranalyzer-dotnet/CSharp/SonarLint.xml).
+The rules from standalone NuGet packages can be enabled or disabled in the same way as the other analyzers based on Roslyn, by using the `.globalconfig` or `.editorconfig` files.
+See: https://learn.microsoft.com/en-us/visualstudio/code-quality/use-roslyn-analyzers?view=vs-2022#set-rule-severity-in-an-editorconfig-file
+
+If the rules are parameterized, the parameter values can be changed using `SonarLint.xml` additional files.
+
+First step is to create a new file, named `SonarLint.xml`, that has the following structure:
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<AnalysisInput xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
+  <Settings>
+    <Setting>
+      <Key>sonar.cs.analyzeGeneratedCode</Key>
+      <Value>false</Value>
+    </Setting>
+  </Settings>
+  <Rules>
+    <Rule>
+      <Key>S107</Key>
+      <Parameters>
+        <Parameter>
+          <Key>max</Key>
+          <Value>2</Value>
+        </Parameter>
+      </Parameters>
+    </Rule>
+  </Rules>
+</AnalysisInput>
+```
+Then, update the projects to include this additional file:
+```xml
+<ItemGroup>
+  <AdditionalFiles Include="SonarLint.xml" />
+</ItemGroup>
+```
