+# Github Actions
+
+Templates for Github Actions workflows I have used for Continuous Testing and Integration can be found in the `.github/workflows` directory.
+
+## Run Unit Tests and Code Coverage
+
+This workflow has the following jobs:
+- run unit tests using `pytest`
+- run code coverage using `coverage` and generating a report published in the PR
+- update the code coverage badge in the `README.md` file
+
+If using this template, you will need to perform the following steps:
+- In [github.com](https://github.com):
+  - add a secret `GIST_SECRET` with read and write access to gists in your repository settings
+  - add a secret to dependabot `GIST_SECRET` with read and write access to gists in your repository settings
+  - create a public gist with the code coverage badge
+  - add `Read and Write` permissions under the repository settings, `Actions` section, to the `GITHUB_TOKEN` secret (allows publishing the coverage report in the PR)
+- In the [workflow file](.github/workflows/run_tests.yml):
+  -  update the `GIST_ID` and `filename` to match the gist you created
+- In the [README.md](README.md):
+  - update the code coverage badge URL to contain the url to the gist you created
+
+Useful links:
+- [Github Action - Dynamic Badges](https://github.com/marketplace/actions/dynamic-badges)
+
+## Publish Docker Image
+
+This workflow has the following jobs:
+- build the docker image
+- publish the docker image to the Github Container Registry and Docker Hub
+
+If using this template, you will need to perform the following steps:
+- In [dockerhub.com](https://hub.docker.com):
+  - create a token with read and write access to your repositories
+- In [github.com](https://github.com):
+  - add a secret `DOCKERHUB_USERNAME` with your Docker Hub username
+  - add a secret `DOCKERHUB_TOKEN` with your Docker Hub token
+- In the [workflow file](.github/workflows/publish_docker_image.yml):
+  - update the `image_name` to match the name of your image
+  - update the `dockerfile` to match the name of your Dockerfile
+  - validate the tags being used

+
+## Contents
+
+- `.github/workflows/`: contains the GitHub Actions workflows.
+- `.vscode/`: contains the settings for Visual Studio Code.
+- `.devcontainer/`: contains the settings for the development container and the development Dockerfile.
+- `app/`: contains the source code of the project.
+- `tests/`: contains the tests of the project.
 
 ## Getting Started
+
+This template relies on using Docker for development and using Visual Studio Code as the IDE.
+
+### Pre-requisites
+- [Docker](https://www.docker.com/)
+- [Visual Studio Code](https://code.visualstudio.com/)
+- [Remote - Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+
+### Step by Step
+To start developing in any repository using this template:
 - Clone the repository
 - Open the repository in VSCode
 - Setup intended Python version in the `Dockerfile.dev`
 - Press `F1` and type `Remote-Containers: Reopen in Container`
-- Start developing
+- Start developing :rocket:
+
+> During this setup, suggested extensions will be installed in the container, and the Python environment will be created, with `pytest`, `coverage`, `poetry` and `black` installed.
 
-## Features
-### Docker-based development
-This is tuned for VSCode and to support container based development.
+### Configuration
 
-You will find the `.vscode` directory with the files needed to make it work. However, before starting to develop, check the `python` version in the `Dockerfile.dev` - ensure you are using a version that suits your needs.
+- [Github Action](Github.md): details needed configuration for the GitHub Actions workflows.
