-## Documentation
+## Getting Started
 
-Please check out full documentation on the [wiki](link to github wiki goes here).
+### Prerequisites
+
+- Ruby version: <%= RUBY_VERSION %>
+<%- if WEB_VARIANT -%>
+- Node version: <%= NODE_VERSION %>
+<%- end -%>
+
+### Docker
+
+- Install [Docker for Mac](https://docs.docker.com/docker-for-mac/install/)
+
+- Setup and boot the Docker containers:
+
+```sh
+./bin/envsetup.sh
+```
+
+### Development
+
+- Setup the databases:
+
+  - Postgres:
+
+  ```sh
+  rake db:setup
+  ```
+
+- Run the Rails app
+
+```sh
+./bin/dev
+```
+
+## Testing
+
+### Docker-based tests on the CI server
+
+Add the following build settings to run the tests in the Docker environment via Docker Compose (configuration in `docker-compose.test.yml`):
+
+- Configure the environment variable `BRANCH_TAG` to tag Docker images per branch, e.g:
+
+```sh
+# a unique `BRANCH_TAG` value to tag the Docker image
+# e.g $SEMAPHORE_BRANCH_ID or using the
+# or using nimblehq/[email protected] Github action
+export BRANCH_TAG= # unique value for tagging Docker image
+```
+
+Each branch needs to have its own Docker image to avoid build settings disparities and leverage Docker image caching.
+
+> BRANCH_TAG must not contain special characters (`/`) to be valid. So using $BRANCH_NAME will not work e.g. chore/setup-docker.
+An alternative is to use a unique identifier such as PR_ID or BRANCH_ID on the CI server.
+
+- Pull the latest version the Docker image for the branch:
+
+```sh
+docker pull $DOCKER_IMAGE:$BRANCH_TAG || true
+```
+
+On each build, the CI environment does not contain yet a cached version of the image. Therefore, it is required to pull
+it first to leverage the `cache_from` settings of Docker Compose which avoids rebuilding the whole Docker image on subsequent test builds.
+
+- Build the Docker image:
+
+```sh
+./bin/docker-prepare && docker compose -f docker-compose.test.yml build
+```
+
+Upon the first build, the whole Docker image is built from the ground up and tagged using `$BRANCH_TAG`.
+
+- Push the latest version of the Docker image for this branch:
+
+```sh
+docker push $DOCKER_IMAGE:$BRANCH_TAG
+```
+
+- Setup the test database:
+
+```sh
+docker compose -f docker-compose.test.yml run test bin/bundle exec rake db:test:prepare
+```
+
+### Test
+
+- Run all tests:
+
+```sh
+# Docker way
+docker compose -f docker-compose.test.yml run test
+
+# Non-Docker way
+rspec
+```
+
+- Run a specific test:
+
+```sh
+# Docker way
+docker compose -f docker-compose.test.yml run test bin/bundle exec rspec [rspec-params]
+
+# Non-Docker way
+rspec [rspec-params]
+```
+
+### Automated Code Review Setup
+- Add a bot (i.e. `team-nimblehq`) to this repository or to the organization. The bot requires permission level “Write” to be able to set a PR’s status.
+
+- Create a [Personal Access Token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
+from bot account with `public_repo` scope, and set it as `DANGER_GITHUB_API_TOKEN` secret on the CI Environment Settings.
+
+## CI/CD
+
+The project relies entirely on [Github Actions](https://github.com/features/actions) for CI/CD via multiple workflows located under the [`.github/workflows/`](.github/workflows) directory.
+
+Please check out the [`.github/workflows/README.md`](.github/workflows/README.md) file for further instructions.
