+# Parameters compile flag
+
+Add `-parameters` flag to your compiler to use all features of LiteCommands:
+Depending on the build system you are using, add the following code to your project:
+
+<tabs group="languages">
+<tab title="Gradle KTS" group-key="gradle">
+
+Add the following line to your `build.gradle.kts` file:
+<br/><br/>
+
+```kotlin
+tasks.withType<JavaCompile> {
+    options.compilerArgs.add("-parameters")
+}
+```
+</tab>
+
+<tab title="Gradle Groovy" group-key="groovy">
+
+Add the following line to your `build.gradle` file:
+<br/><br/>
+
+```kotlin
+tasks.withType(JavaCompile) {
+    options.compilerArgs << "-parameters"
+}
+```
+</tab>
+
+<tab title="Maven" group-key="maven">
+
+Add the following lines to your `pom.xml` file in the `plugins` section:
+<br/><br/>
+
+```xml
+<plugin>
+    <groupId>org.apache.maven.plugins</groupId>
+    <artifactId>maven-compiler-plugin</artifactId>
+    <version>3.11.0</version>
+    <configuration>
+        <compilerArgs>
+            <arg>-parameters</arg>

+    </configuration>
+</plugin>
+```

+<tip>
+Parameters are used to get the name of the parameter in the method. 
+Without this flag, the name of the command arguments will be <code>arg0</code>, <code>arg1</code>, etc. 
+
+Also you can define the name of the parameter in the <code>@Arg("name")</code> annotation.
