== Updating `pkl.impl.ghactions`
19+
20+
There is a script in `./scripts/update_downstream_ci.sh` that auto-bumps the `pkl.impl.ghactions` package in every downstream repository.
21+
22+
This script should be run whenever a new package is published.
23+
24+
This tool assumes:
25+
26+
1. You have `pkl`, `jq`, and `gh` installed.
27+
2. You are logged into `gh`.
28+
3. You have every downstream repo forked onto your personal GitHub account.
