+
+[![style: very good analysis][very_good_analysis_badge]][very_good_analysis_link]
+[![Powered by Mason](https://img.shields.io/endpoint?url=https%3A%2F%2Ftinyurl.com%2Fmason-badge)](https://github.com/felangel/mason)
+[![License: MIT][license_badge]][license_link]
+
+A Very Good Project created by Very Good CLI.
+
+## Installation 💻
+
+**❗ In order to start using Lite Ref Core you must have the [Dart SDK][dart_install_link] installed on your machine.**
+
+Install via `dart pub add`:
+
+```sh
+dart pub add lite_ref_core
+```
+
+---
+
+## Continuous Integration 🤖
+
+Lite Ref Core comes with a built-in [GitHub Actions workflow][github_actions_link] powered by [Very Good Workflows][very_good_workflows_link] but you can also add your preferred CI/CD solution.
+
+Out of the box, on each pull request and push, the CI `formats`, `lints`, and `tests` the code. This ensures the code remains consistent and behaves correctly as you add functionality or make changes. The project uses [Very Good Analysis][very_good_analysis_link] for a strict set of analysis options used by our team. Code coverage is enforced using the [Very Good Workflows][very_good_coverage_link].
+
+---
+
+## Running Tests 🧪
+
+To run all unit tests:
+
+```sh
+dart pub global activate coverage 1.2.0
+dart test --coverage=coverage
+dart pub global run coverage:format_coverage --lcov --in=coverage --out=coverage/lcov.info
+```
+
+To view the generated coverage report you can use [lcov](https://github.com/linux-test-project/lcov).
+
+```sh
+# Generate Coverage Report
+genhtml coverage/lcov.info -o coverage/
+
+# Open Coverage Report
+open coverage/index.html
+```
