+# Inclusion criteria for services

+After creating you own service you will need to submit it to our [NewPipeExtractor](https://github.com/teamnewpipe/newpipeextractor)
+ repository. However in order to include your changes you need to follow certain rules.
+
+1. Stick to our [Code contribution guidelines](https://github.com/TeamNewPipe/NewPipe/blob/dev/.github/CONTRIBUTING.md#code-contribution)
+2. Do not send services that present content we [don't allow](#not-allowed-content) on NewPipe.
+3. You need to be willing to keep on maintaining your service after submission.
+4. Be patient and do the requested changes when one of our maintainers rejects your code.
