Welcome to the wonderful world of extending Sling. Refer to these pages to find out how we envision the extension of Sling and how to do it. See also [Developing for Sling](https://cwiki.apache.org/confluence/display/SLING/Developing+for+Sling) on the Sling Wiki, which has more information on specific topics. ## Using Sling as your Development Framework Look here for more information on developer support when your are using Sling to build your own applications. * [Getting and Building Sling](/documentation/development/getting-and-building-sling.html) * [Defining and Launching a Sling based Application](/documentation/development/slingstart.html) * [Content-Package based development](/documentation/development/content-packages.html) * [Embedding Sling](/documentation/development/embedding-sling.html) * [Logging](/documentation/development/logging.html) * [Client Request Logging](/documentation/development/client-request-logging.html) * [Monitoring Requests](/documentation/development/monitoring-requests.html) * [Repository Based Development](/documentation/development/repository-based-development.html) * [Sling IDE Tooling](/documentation/development/ide-tooling.html) * [Leveraging @NotNull/@Nullable null annotations](/documentation/development/null-analysis.html) ## Testing Sling-based Applications * [Testing Sling-based Applications](/documentation/tutorials-how-tos/testing-sling-based-applications.html) * [Testing with Pax Exam](/documentation/development/testing-paxexam.html) * [Junit Server-Side Tests Support](/documentation/bundles/org-apache-sling-junit-bundles.html) * [Resource Resolver Mock](/documentation/development/resourceresolver-mock.html) * [Sling Mocks](/documentation/development/sling-mock.html) * [OSGi Mocks](/documentation/development/osgi-mock.html) * [JCR Mocks](/documentation/development/jcr-mock.html) * [Hamcrest integration](/documentation/development/hamcrest.html) ## Maven Stuff Sling is using Apache Maven 3 as its build system.
