 On a very high level, Spring for Apache Pulsar provides a `PulsarTemplate` for publishing to a Pulsar topic and a `PulsarListener` annotation for consuming from a Pulsar topic.
 In addition, it also provides various convenience APIs for Spring developers to ramp up their development journey into Apache Pulsar.

+= Pulsar Clients and Spring Boot Compatibility
+
+include::attributes.adoc[]
+
+The following is the compatibility matrix:
+|===
+| Spring for Apache Pulsar | Pulsar Client | Pulsar Reactive Client | Spring Boot | Java
+
+| 1.0.x
+| 3.0.x
+| 0.3.x
+| 3.2.x
+| 17+
+
+| 0.2.x
+| 2.11.x
+| 0.2.x
+| 3.0.x / 3.1.x^**(*)**^
+| 17+
+|===
+
+
+NOTE: In version `1.0.0` the auto-configuration moved into Spring Boot `3.2.x` and therefore `3.2.x` is the minimum Spring Boot version supported when using version `1.0.x` of the framework.
+Prior to version `1.0.0`, the auto-configuration support exists in the framework itself.
+^**(*)**^This makes it theoretically possible to use later versions of Spring Boot besides `3.0.x` which it is tested against and guaranteed to work with. In other words, it may work with `3.1.x` but it has not been tested against it.
