Open Integration Hub is a framework which you can run on your own infrastructure and in different compositions, depending on your use case. This flexibility can be challenging in the beginning.
To help you getting started, we created two guides for running Open Integration Hub locally and on Google Cloud Platform. We also walk you trough creating your first flow. If you first want to understand more about how it actually works, we suggest you start with the Service Collaboration Overview.
In case you need help or want to give us some feedback, head over to GitHub.
