+Replace the `latest` tag with a specific version image tag from [`cypress/browsers` on Docker Hub](https://hub.docker.com/r/cypress/browsers/tags) to avoid breaking changes when new images are released (especially when they include new major versions of Node.js).
+
+Include `options: --user 1001` to avoid permissions issues.
+
+Refer to [cypress-io/cypress-docker-images](https://github.com/cypress-io/cypress-docker-images) for further information about using Cypress Docker images. Cypress offers the [Cypress Docker Factory](https://github.com/cypress-io/cypress-docker-images/tree/master/factory) to generate additional Docker images with selected components and versions.
