Setup

By including preferably a one-liner or if necessary a set of clear CLI instructions we improve user experience. This should be a frictionless installation process that works on various operating systems (macOS, Linux, Windows WSL) and handles all the dependencies.

Clone the repository

git clone https://github.com/NHSDigital/nhs-notify-admail/
cd  NHSDigital/nhs-notify-admail/

Prerequisites

The following software packages, or their equivalents, are expected to be installed and configured:

• Docker container runtime or a compatible tool, e.g. Podman,
• asdf version manager,
• GNU make 3.82 or later,

Note

The version of GNU make available by default on macOS is earlier than 3.82. You will need to upgrade it or certain make tasks will fail. On macOS, you will need Homebrew installed, then to install make, like so:

brew install make

You will then see instructions to fix your $PATH variable to make the newly installed version available. If you are using dotfiles, this is all done for you.

• GNU sed and GNU grep are required for the scripted command-line output processing,
• GNU coreutils and GNU binutils may be required to build dependencies like Python, which may need to be compiled during installation,

Note

For macOS users, installation of the GNU toolchain has been scripted and automated as part of the dotfiles project. Please see this script for details.

• Python required to run Git hooks,
• jq a lightweight and flexible command-line JSON processor.

Configuration

Installation and configuration of the toolchain dependencies

make config

Usage

After a successful installation, provide an informative example of how this project can be used. Additional code snippets, screenshots and demos work well in this space. You may also link to the other documentation resources, e.g. the User Guide to demonstrate more use cases and to show more features.

Testing

There are make tasks for you to configure to run your tests. Run make test to see how they work. You should be able to use the same entry points for local development as in your CI pipeline.

Design

Diagrams

The C4 model is a simple and intuitive way to create software architecture diagrams that are clear, consistent, scalable and most importantly collaborative. This should result in documenting all the system interfaces, external dependencies and integration points.

The source for diagrams should be in Git for change control and review purposes. Recommendations are draw.io (example above in docs folder) and Mermaids. Here is an example Mermaids sequence diagram:

sequenceDiagram
    User->>+Service: GET /users?params=...
    Service->>Service: auth request
    Service->>Database: get all users
    Database-->>Service: list of users
    Service->>Service: filter users
    Service-->>-User: list[User]

Modularity

Most of the projects are built with customisability and extendability in mind. At a minimum, this can be achieved by implementing service level configuration options and settings. The intention of this section is to show how this can be used. If the system processes data, you could mention here for example how the input is prepared for testing - anonymised, synthetic or live data.

Contributing

Describe or link templates on how to raise an issue, feature request or make a contribution to the codebase. Reference the other documentation files, like

• Environment setup for contribution, i.e. CONTRIBUTING.md
• Coding standards, branching, linting, practices for development and testing
• Release process, versioning, changelog
• Backlog, board, roadmap, ways of working
• High-level requirements, guiding principles, decision records, etc.

Contacts

Provide a way to contact the owners of this project. It can be a team, an individual or information on the means of getting in touch via active communication channels, e.g. opening a GitHub discussion, raising an issue, etc.
