 - The scope of the pull request is not too large. Please consider separate pull requests for each feature as big pull requests are very time consuming to understand.
 
 We will provide feedback on your pull requests as soon as possible. Following the tips above will help ensure your changes are reviewed.

+### Testing contribution pull requests
+
+OHIF uses [netlify](netlify.com) so that pull requests are autogenerated and available for testing.
+
+For example, [this url](https://deploy-preview-235--ohif.netlify.com/viewer/?url=https://s3.eu-central-1.amazonaws.com/ohif-viewer/sampleDICOM.json) allows you to test [pull request 235](https://github.com/OHIF/Viewers/pull/235) using data pulled from Amazon S3.
+
+Replacing the number 235 in the link below with your pull request number should let you test it as well and you can use this link for discussions on github without requiring reviewers to download and build your branch.
