+# This folder contains GitHub Actions workflows for building the project
+
+## backend-pr
+Runs: when a pull request targets the master branch and changes the libs/ and/or backend/ folders
+
+This workflow uses the actions docker/setup-qemu-action@v1 and docker/setup-buildx-action@v1 to prepare the environment for aarch64 cross complilation using docker buildx.
+A matrix-strategy has been used for building the v8 snapshot instead of the makefile to allow parallel job execution.
+
+## frontend-pr
+Runs: when a pull request targets the master branch and changes the frontend/ folder
+
+This workflow builds the frontends.
+
+## product
+Runs: when a change to the master branch is made
+
+This workflow builds everything, re-using the backend-pr and frontend-pr 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.

 - `system-images` - (Docker, Rust) A suite of utility Docker images that are preloaded with EmbassyOS to assist with functions relating to services (eg. configuration, backups, health checks).
-- [`setup-wizard`] (ui/README.md)- Code for the user interface that is displayed during the setup and recovery process for EmbassyOS.
-- [`diagnostic-ui`] (diagnostic-ui/README.md) - Code for the user interface that is displayed when something has gone wrong with starting up EmbassyOS, which provides helpful debugging tools.

 This project aims to have a clean git history, where code changes are only made in non-merge commits. This simplifies auditability because merge commits can be assumed to not contain arbitrary code changes.
