+# This folder contains GitHub Actions workflows for building the project
+
+## backend
+Runs: manually (on: workflow_dispatch) or called by product-pipeline (on: workflow_call)
+
+This workflow uses the actions and docker/setup-buildx-action@v1 to prepare the environment for aarch64 cross complilation using docker buildx.
+When execution of aarch64 containers is required the action docker/setup-qemu-action@v1 is added.
+A matrix-strategy has been used to build for both x86_64 and aarch64 platforms in parallel.
+
+### Running unittests
+
+Unittests are run using [cargo-nextest]( https://nexte.st/). First the sources are (cross-)compiled and archived. The archive is then run on the correct platform.
+
+## frontend
+Runs: manually (on: workflow_dispatch) or called by product-pipeline (on: workflow_call)
+
+This workflow builds the frontends.
+
+## product
+Runs: when a pull request targets the master or next branch and when a change to the master or next branch is made
+
+This workflow builds everything, re-using the backend and frontend workflows.
+The download and extraction order of artifacts is relevant to `make`, as it checks the file timestamps to decide which targets need to be executed.
+
+Result: eos.img
+
+## a note on uploading artifacts
+
+Artifacts are used to share data between jobs. File permissions are not maintained during artifact upload. Where file permissions are relevant, the workaround using tar has been used. See (here)[https://github.com/actions/upload-artifact#maintaining-file-permissions-and-case-sensitive-files].

 ### Project Structure
-EmbassyOS is composed of the following components. Please visit the README for each component to understand the dependency requirements and installation instructions.
-- [`ui`](ui/README.md) (Typescript Ionic Angular) is the code that is deployed to the browser to provide the user interface for EmbassyOS.
-- [`backend`] (backend/README.md) (Rust) is a command line utility, daemon, and software development kit that sets up and manages services and their environments, provides the interface for the ui, manages system state, and provides utilities for packaging services for EmbassyOS.
