 ### Changes

 - added GitHub templates for PRs and issues
 - Added linting using Black, Flake8, and iSort. This necessitated the addition of a `setup.cfg` file, so an additional linter, `setup-cfg-fmt` was added to check that file. These linters are all pre-commit hooks, so will force any future commits to abide by our style. [#20](https://github.com/firebolt-db/dbt-firebolt/pull/20)
+- indefinitely removed `setup.cfg` from project [#29](https://github.com/firebolt-db/dbt-firebolt/pull/29)
