First, open a task to see the Protocol steps overview and start making changes to the protocol. After you are finished with editing the parent protocol, you have to save it in the Protocols repository with a different name, so you don’t lose its original content. This way you can create different versions of the parent protocol (i.e. child protocols) as seen in the image below.
Once the protocols are saved under the Public protocols tab in the Protocols repository, they can be available to other team members and be reused (loaded) in other tasks.
