+## Platforms
+
+Cypress Docker images are Linux based, using the Docker image [debian:12-slim](https://hub.docker.com/_/debian) as the default base image. Each of the above listed Cypress Docker images is published with [multi-architecture](https://docs.docker.com/contribute/style/terminology/#multi-architecture--multi-arch) support for `Linux/amd64` and `Linux/arm64` platforms.
+
+Note that `Linux/arm64` variants of [cypress/browsers](./browsers/) and [cypress/included](./included/) images do **not** contain additional browsers (see related Enhancement Request [#695](https://github.com/cypress-io/cypress-docker-images/issues/695)).
+
+Cypress Docker images can be run as containers on Continuous Integration (CI) systems which support Docker. Cypress Docker images can also be run locally under [Docker Desktop](https://docs.docker.com/desktop/) for Mac, Linux or Windows environments.
+
+ In the case of Windows environments, see [Docker Desktop for Windows](https://docs.docker.com/desktop/install/windows-install/) and Cypress documentation [Windows Subsystem for Linux](https://on.cypress.io/guides/references/advanced-installation#Windows-Subsystem-for-Linux) for additional information regarding Microsoft's `WSL2` and `WSLg` subsystems. The documentation and scripts in this repository assume that Docker Desktop for Windows runs in a virtual Linux environment.
+
 ## Tag Selection
 
 If no tag is specified, for example `cypress/included`, then the tag `latest` is used by default: `cypress/included:latest`. It is however recommended to use a specific image tag to avoid breaking changes when new images are released, especially when they include new major versions of Node.js or Cypress.
