What does IntelliJ's deployment.xml do? Follow

Can anyone tell me what deployment.xml in .idea folder does? We have a team of developers sharing IntelliJ configurations for ease of setup. This file seems to be changed on some developers' environments. I'm trying to figure out if it's ok to share across or should be added to our .gitignore. I found the doc that states we can share everything in the .idea folder except workspace.xml and tasks.xml but the changes in this file look like they're specific to a developer's local environment so I don't want to push it out to everyone if that is the case.
