What is the .idea folder?

The .idea folder (hidden on OS X) in the solution root contains IntelliJ’s project specific settings files. These include per-project details such as VCS mapping and run and debug configurations, as well as per-user details, such as currently open files, navigation history and currently selected configuration.

Some files should be committed to source control, some should be excluded. Please refer to this JetBrains.gitignore on GitHub to see what should be ignored.
