+= Groups page
+
+[role="_abstract"]
+The *Groups* page lists all groups associated with a Kafka cluster.
+Groups represent client applications that coordinate work across multiple instances.
+
+You can filter the list by group name, type, or status.
+
+Kafka supports the following group types:
+
+* *Consumer groups* coordinate message consumption across multiple consumer instances. Each consumer in the group processes a subset of topic partitions.
+* *Classic groups* use the original Kafka consumer group protocol used by earlier Kafka consumer clients.
+* *Streams groups* are created by Kafka Streams applications to coordinate stream processing tasks.
+* *Share groups* distribute message processing across multiple consumers using a shared consumption model. Multiple consumers can process messages from the same partition concurrently.
+
+Apache Kafka introduced a newer consumer group protocol in version 4.0. 
+Clients that use this protocol appear as *Consumer* groups in the console, while clients that use the original protocol appear as *Classic* groups.
+Streams groups and Share groups were introduced in Apache Kafka 4.2.
+
+For each group, the page shows information such as the group type and membership.
+The console also displays the overall consumer lag across partitions and the number of members.
+Click associated topics to view topic information available from the xref:con-topics-page-{context}[*Topics* page tabs].
+
+Group status indicates the current state of a group.
+The exact states that appear depend on the group type.
+
+Common states include:
+
+* *Stable* indicates normal operation.
+* *Empty* indicates that the group exists but currently has no active members.
+* *Dead* indicates that the group is being removed after all members have left and retention has expired.
+
+Some group types might display additional states depending on the group protocol:
+
+* *PreparingRebalance* and *CompletingRebalance* can appear for Classic and Consumer groups while partition assignments are being updated.
+* *Assigning* can appear for Consumer and Streams groups when a new partition assignment has been calculated but has not yet been applied to all members.
+* *Reconciling* can appear for Consumer and Streams groups while members are transitioning to their assigned partitions.
+* *NotReady* can appear for Streams groups when the application topology or required topics are not yet ready for processing.
+
+Click a group name to view group details and membership information.
+Select the options icon (three vertical dots) for a consumer group to reset consumer offsets.
+
+NOTE: Resetting offsets is supported only for consumer groups. 
+Streams groups and Share groups do not currently support offset reset operations.
