There are two code style files within codestyles. The directory is intended to be a drop-in replacement within the .idea folder of a project, which will expose both code styles as selectable schemes.

The Project.xml code style is intended to be added to a project in IntelliJ, living in <project>/.idea/codestyles as described above.

The Stellar.xml code style is intended to be an IDE-level code style within IntelliJ but can also be used as a project style by placing it in the same location described above. This code style has not well tested ever since IntelliJ stopped supporting the "codestyle-from-remote-source" functionality. Additionally, it originally came from IntelliJ Ultimate.
