In many game jams, it can be difficult to find time to build and test your project. Continous Intergration can go through that process for you so when you are ready for release, you can just download your builds directly from Unity without having to wait around.

Continous intergration combined with some sort of version control and can make collaborative development and testing a whole lot simplier. With Unity's Cloud Build product, you can create a basic pipeline for your application in no time.

While you can get CI to work with other game engines, Unity Cloud Build, and this blog is focused on Unity. If you have questions on getting CI to work on another engine, shoot me a message on discord. :thumbsup:

Note: Unity Cloud Build requires Unity Teams Advances which requires either Unity Pro or a $9 subscription.

If you have 0 experince with GIT or version control, I suggest taking a look at GitHub for Unity.
