+= Deploying Lite Members
+
+Use the Hazelcast Platform Operator to deploy link:https://docs.hazelcast.com/hazelcast/latest/maintain-cluster/lite-members[Lite Members]. You can use the separate `liteMember` section in the Hazelcast CR.
+
+WARNING: When `jvm`, `env`, `resources`, `scheduling` sections are configured in the Hazelcast CR, it will not affect the lite member configuration. Lite members must be configured as explained in the following sections.
+
+== Configuring the Number of Lite Members
+
+To configure the number of lite members you want to deploy in the Hazelcast CR, use the `count` field in the `liteMember` section of the Hazelcast CR.
+
+.Example Lite Member Count Configuration
+[source,yaml,subs="attributes+"]
+----
+include::ROOT:example$/lite-member.yaml[]
+----
+
+When you apply the given example, 3 data members and 2 lite members are deployed.
+
+NOTE: As seen in the example, `clusterSize` represents the number of data members to be created.
+
+== Configuring JVM Parameters
+
+To configure JVM Parameters specifically for lite members, you can use the `jvm` field in the `liteMember` section of the Hazelcast CR.
+
+.Example Lite Member JVM Configuration
+[source,yaml,subs="attributes+"]
+----
+include::ROOT:example$/lite-member-jvm.yaml[]
+----
+
+== Configuring Environment Variables
+
+To configure environment variables specifically for lite members, you can use the `env` field in the `liteMember` section of the Hazelcast CR.
+
+Same rules and logic is applicable as in the xref:env-vars.adoc[Environment variables].
+
+== Configuring Resource Limits
+
+To configure resource limits specifically for lite members, you can use the `resources` field in the `liteMember` section of the Hazelcast CR.
+
+.Example Lite Member Resource Limits Configuration
+[source,yaml,subs="attributes+"]
+----
+include::ROOT:example$/lite-member-resource-limits.yaml[]
+----
+
+== Configuring Scheduling
+
+To configure scheduling specifically for lite members, you can use the `scheduling` field in the `liteMember` section of the Hazelcast CR.
+
+.Example Lite Member Scheduling Configuration
+[source,yaml,subs="attributes+"]
+----
+include::ROOT:example$/lite-member-scheduling.yaml[]
