+# Deploying a build to UE
+
+## Build
+
+Builds are produced via GitHub CI (Action Runners) and uploaded as artifacts
+to GitHub. See [create_release.yml](.github/workflows/create_release.yml) for
+details on what happens during the build.
+
+A new release is created when the [VERSION.txt](VERSION.txt) file changes.
+
+## Deploying into the UE tree
+
+After a successful release, you need to integrate the resulting binaries into
+the UE tree. There's a helper script for this in [scripts/download_artifacts.py](scripts/download_artifacts.py)
+
+You'll need a p4 workspace mapped to the stream or branch you want to deploy
+into, and a clone of the zen git repo. Since we use `gh` to download the 
+artifacts you'll need to use `gh auth login` and `gh repo clone` to clone
+the repo. With the current directory set to the root of the cloned git repo, 
+run the following command to download the artifacts corresponding to the 
+VERSION.txt in the repo by default.
+
+```bash
+> python scripts/download_artifacts.py <UE root path>
+```
+
+The script should go ahead and for each platform downloads the artifacts 
+using `gh artifact download` to a temporary directory, sync the corresponding
+files in Engine/Binaries/<platform> to #head and opens them for edit and
+copies the downloaded binaries into place, leaving the changes in your default
+changelist.
