Acquiring Lumberyard source

Each release of Lumberyard exists as a separate branch in GitHub. You can get Lumberyard from GitHub using the following steps:

Fork the repository

Forking creates a copy of the Lumberyard repository in your GitHub account. Your fork becomes the remote repository into which you can push changes.

Create a branch

The GitHub workflow assumes your master branch is always deployable. Create a branch for your local project or fixes.

For more information about branching, see the GitHub documentation.

Clone the repository

Cloning the repository copies your fork onto your computer. To clone the repository, click the "Clone or download" button on the GitHub website, and copy the resultant URL to the clipboard. In a command line window, type git clone [URL], where [URL] is the URL that you copied in the previous step.

For more information about cloning a reposity, see the GitHub documentation.

Downloading additive files

Once the repository exists locally on your machine, manually execute git_bootstrap.exe found at the root of the repository. This application will perform a download operation for Lumberyard binaries that are required prior to using or building the engine. This program uses AWS services to download the binaries. Monitor the health of AWS services on the AWS Service Health Dashboard.

Running the Setup Assistant

git_bootstrap.exe will launch the Setup Assistant when it completes. Setup Assistant lets you configure your environment and launch the Lumberyard Editor.
