# Use filters

Filter are a way to disable behaviors of commands. They are executed before commands, if the filter's condition is true, the command won't be executed.

```java
JDA jda = JDABuilder.createDefault("your token").build();
        
new LightDrop().hook(jda)
    .map(new MyCommand())
    .filter(context -> context.getMessage().getContentRaw().contains("Hello"));
```
