 # dbt-score
+
+Linter for dbt model metadata.
+
+## Development
+
+### Prerequisites
+
+You'll need the following prerequisites:
+
+* Any Python version starting from 3.10
+* [pre-commit](https://pre-commit.com/)
+* [PDM](https://pdm-project.org/2.12/)
+
+Configure development environment running these commands from the project's root:
+
+```shell
+pre-commit install
+pdm install --group :all
+```
+
+### Lint
+
+`dbt_score` uses:
+* [ruff](https://docs.astral.sh/ruff/) for fast linting and formatting.
+* [mypy](https://mypy.readthedocs.io/en/stable/) for type checking.
+* [pre-commit-hooks](https://github.com/pre-commit/pre-commit-hooks).
+
+Cheatsheet:
+
+```shell
+pdm run ruff check .
+pdm run ruff check --fix
+pdm run mypy .
+pre-commit run --all-files
+pdm run tox -e lint
+```
+
+### Test
+
+`dbt_score` uses:
+* [pytest](https://docs.pytest.org/) as a main test framework.
+* [coverage](https://coverage.readthedocs.io/en/latest/index.html) for test coverage.
+* [tox](https://tox.wiki/en/latest/) for testing against multiple Python versions.
+
+Cheatsheet:
+
+```shell
+pdm run tox -e py
+pdm run pytest
+pdm run coverage run -m pytest
+```
+
+### Docs
+
+`dbt_score` uses:
+* [mkdocs](https://www.mkdocs.org/) for docs generation.
+* [mkdocstrings](https://mkdocstrings.github.io/) for automatic docs from sources.
+
+Cheatsheet:
+
+```shell
+pdm run mkdocs build
+pdm run mkdocs serve
+```
