+First, add dependency <literal>com.paypal.springboot:resteasy-spring-boot-starter</literal> to your Spring Boot application. It is recommended to you use <ulink url="http://search.maven.org/#search%7Cga%7C1%7Cg:com.paypal.springboot">the latest version</ulink>.
+Second, optionally you can register one or more JAX-RS application classes. To do so, just define it as a Spring bean, and it will be automatically registered. See the example below.

+As noted in <xref linkend="upgrading-wildfly"/>, the RESTEasy distribution comes with a zip file called resteasy-jboss-modules-&lt;version&gt;.zip,
 which can be unzipped into the modules/system/layers/base/ directory of WildFly to upgrade to a new version of RESTEasy.
 Because of the way resteasy-spring is used in WildFly, after unzipping the zip file, it is also necessary to remove the
 old resteasy-spring jar from modules/system/layers/base/org/jboss/resteasy/resteasy-spring/main/bundled/resteasy-spring-jar.
