 ### A copy of Agones source code
 If you don't already have a local copy of the Agones source code you can either (1) clone the official [googleforgames/agones repository](https://github.com/googleforgames/agones) for quicker access or (2) create a fork then clone your fork. Make note of where you clone the project to for the next setup steps!
