# Description

<!--
Explain this PR in as much detail as applicable

Some example prompts to consider:
How might this affect the game? The codebase?
What might be some alternatives to this?
How/Who does this benefit/hurt [the game/codebase]?
-->

The EE logo was still attributed to me, and the source files weren't
included here.
