 Alternatively, you can also download the layer artifact from one of our [CI workflow runs](https://github.com/Sparticuz/chromium/actions/workflows/aws.yml?query=is%3Asuccess+branch%3Amaster). Use the `chromium.zip` INSIDE the artifact as the layer. Also, the artifact will expire from Github after a certain time period.
