 - When making additions to the project, consider if the majority of users will benefit from your change. If not, you're probably better of forking the project.
 - Also consider if your change will get in the way of other users. A good change is a change that enhances the experience of some users who want that change and does not affect users who do not care about the change.
 - Please see the [paperless-ngx merge process](#merging-prs) below.
