 # Syncing downstream OLM
 
-All of the staged repositories live in the top level `staging` directory. The versions of each staged dependency are tracked in the [`scripts/tracked`](./tracked) file.
+All of the staged repositories live in the top level `staging` directory.
 
-## Setup
-
-The sync process requires the git-subtree command. See [git subtree](https://github.com/git/git/blob/master/contrib/subtree/INSTALL) for more detailed instructions.
-
-The local repo also needs to track the upstream remotes in [`scripts/tracked`](./tracked). To add these to your repo, run the `init_remotes` script from the root of your repo:
-
-```bash
-./scripts/init_remotes.sh
-```
-
-## Syncing with upstream
-
-To sync a staged dependency with an upstream version, you can use the `pull_upstream.sh` helper script. This adds a staged repo if it is not present and updates it to the provided tag/branch otherwise. The script is run as follows:
-
-```bash
-./scripts/pull_upstream.sh <remote url or name> [<ref>]
-```
-
-The ref can be a valid tag or branch on the remote, and defaults to master. A successful run adds a new commit to the current branch, similar to
-
-```text
-1bec1e8bb Sync upstream api v0.6.1
-```
-
-Commit history for the staged repositories is not preserved. The latest synced upstream commit for each staged repo can be found in the `./scripts/tracked` file.
-
-Once the sync is completed, verify it by running the unit tests for the dependencies.
-
-## Pushing changes upstream
-
-Changes made to the staged repositories may be pushed upstream by providing specific commit ranges. For this run:
-
-```bash
-./scripts/push_upstream.sh <remote name> <commit range or list>
-```
-
-This creates a local branch containing from the last synced version of the staged dependency with the specified commits cherry-picked onto it. You can then create a PR from this branch to the required upstream repository.
+Note: the process for porting upstream commits downstream is outlined in the [OLM downstreaming guide](https://docs.google.com/document/d/139yXeOqAJbV1ndC7Q4NbaOtzbSdNpcuJan0iemORd3g/edit#).
