 # Configure Fluent Bit using classic mode
 
+{% hint style="info" %}
 Fluent Bit classic mode configuration will be deprecated at the end of 2026.
+{% endhint %}
 
 Classic mode is a custom configuration model for Fluent Bit. It's more limited than the [YAML configuration mode](../configuring-fluent-bit/yaml.md), and doesn't have the more extensive feature support the YAML configuration has. Classic mode basic design only supports grouping sections with key-value pairs and lacks the ability to handle sub-sections or complex data structures like lists.
