-# **what?**
-# This workflow models the performance characteristics of a point in time in dbt.
-# It runs specific dbt commands on committed projects multiple times to create and
-# commit information about the distribution to the current branch. For more information
-# see the readme in the performance module at /performance/README.md.
-#
-# **why?**
-# When developing new features, we can take quick performance samples and compare
-# them against the commited baseline measurements produced by this workflow to detect
-# some performance regressions at development time before they reach users.
-#
-# **when?**
-# This is only run once directly after each release (for non-prereleases). If for some
-# reason the results of a run are not satisfactory, it can also be triggered manually.

 ### Invoking dbt
 
 The "tasks" map to top-level dbt commands. So `dbt run` => task.run.RunTask, etc. Some are more like abstract base classes (GraphRunnableTask, for example) but all the concrete types outside of task should map to tasks. Currently one executes at a time. The tasks kick off their “Runners” and those do execute in parallel. The parallelism is managed via a thread pool, in GraphRunnableTask.
@@ -40,16 +35,15 @@ Each adapter plugin is a standalone python package that includes:
 
 - `dbt/include/[name]`: A "sub-global" dbt project, of YAML and SQL files, that reimplements Jinja macros to use the adapter's supported SQL syntax
 - `dbt/adapters/[name]`: Python modules that inherit, and optionally reimplement, the base adapter classes defined in dbt-core
-- `setup.py`
+- `pyproject.toml`
 
 The Postgres adapter code is the most central, and many of its implementations are used as the default defined in the dbt-core global project. The greater the distance of a data technology from Postgres, the more its adapter plugin may need to reimplement.
 
 ## Testing dbt
 
-The [`test/`](test/) subdirectory includes unit and integration tests that run as continuous integration checks against open pull requests. Unit tests check mock inputs and outputs of specific python functions. Integration tests perform end-to-end dbt invocations against real adapters (Postgres, Redshift, Snowflake, BigQuery) and assert that the results match expectations. See [the contributing guide](CONTRIBUTING.md) for a step-by-step walkthrough of setting up a local development and testing environment.

 - [GitHub Actions](https://github.com/features/actions) for automating tests and checks, once a PR is pushed to the `dbt-core` repository
 
 A deep understanding of these tools in not required to effectively contribute to `dbt-core`, but we recommend checking out the attached documentation if you're interested in learning more about each one.
 
 #### Virtual environments
 
-We strongly recommend using virtual environments when developing code in `dbt-core`. We recommend creating this virtualenv
-in the root of the `dbt-core` repository. To create a new virtualenv, run:
-```sh
-python3 -m venv env
-source env/bin/activate
-```
+dbt-core uses [Hatch](https://hatch.pypa.io/) for dependency and environment management. Hatch automatically creates and manages isolated environments for development, testing, and building, so you don't need to manually create virtual environments.
 
-This will create and activate a new Python virtual environment.
+For more information on how Hatch manages environments, see the [Hatch environment documentation](https://hatch.pypa.io/latest/environment/).

 ### Installation
 
-First make sure that you set up your `virtualenv` as described in [Setting up an environment](#setting-up-an-environment).  Also ensure you have the latest version of pip installed with `pip install --upgrade pip`. Next, install `dbt-core` (and its dependencies):
+First make sure you have Python 3.10 or later installed. Ensure you have the latest version of pip installed with `pip install --upgrade pip`. Next, install `hatch`.  Finally set up `dbt-core` for development:
 
 ```sh
-make dev
+cd core
+hatch run setup
 ```
-or, alternatively:
+
+This will install all development dependencies and set up pre-commit hooks.
+
+By default, hatch will use whatever Python version is active in your environment. To specify a particular Python version, set the `HATCH_PYTHON` environment variable:
+
 ```sh
-pip install -r dev-requirements.txt -r editable-requirements.txt
-pre-commit install
+export HATCH_PYTHON=3.12
+hatch env create
 ```
 
+Or add it to your shell profile (e.g., `~/.zshrc` or `~/.bashrc`) for persistence.
+
 When installed in this way, any changes you make to your local copy of the source code will be reflected immediately in your next `dbt` run.
 
+#### Building dbt-core
+
+dbt-core uses [Hatch](https://hatch.pypa.io/) (specifically `hatchling`) as its build backend. To build distribution packages:
+
+```sh
+cd core
+hatch build
+```
+
+This will create both wheel (`.whl`) and source distribution (`.tar.gz`) files in the `dist/` directory.
+
+The build configuration is defined in `core/pyproject.toml`. You can also use the standard `python -m build` command if you prefer.
+
 ### Running `dbt-core`
 
-With your virtualenv activated, the `dbt` script should point back to the source code you've cloned on your machine. You can verify this by running `which dbt`. This command should show you a path to an executable in your virtualenv.
+Once you've run `hatch run setup`, the `dbt` command will be available in your PATH. You can verify this by running `which dbt`.
 
 Configure your [profile](https://docs.getdbt.com/docs/configure-your-profile) as necessary to connect to your target databases. It may be a good idea to add a new profile pointing to a local Postgres instance, or a specific test sandbox within your data warehouse if appropriate. Make sure to create a profile before running integration tests.

 ```
 
 ### Test commands
 
 There are a few methods for running tests locally.
 
-#### Makefile
+#### Hatch scripts
 
-There are multiple targets in the Makefile to run common test suites and code
-checks, most notably:
+The primary way to run tests and checks is using hatch scripts (defined in `core/hatch.toml`):
 
 ```sh
-# Runs unit tests with py38 and code checks in parallel.
-make test
-# Runs postgres integration tests with py38 in "fail fast" mode.
-make integration
-```
-> These make targets assume you have a local installation of a recent version of [`tox`](https://tox.readthedocs.io/en/latest/) for unit/integration testing and pre-commit for code quality checks,
-> unless you use choose a Docker container to run tests. Run `make help` for more info.
+cd core
 
-Check out the other targets in the Makefile to see other commonly used test
-suites.
+# Run all unit tests
+hatch run unit-tests
+
+# Run unit tests and all code quality checks
+hatch run test
+
+# Run integration tests
+hatch run integration-tests
+
+# Run integration tests in fail-fast mode
+hatch run integration-tests-fail-fast
+
+# Run linting checks only
+hatch run lint
+hatch run flake8
+hatch run mypy
+hatch run black
+
+# Run all pre-commit hooks
+hatch run code-quality
+
+# Clean build artifacts
+hatch run clean
+```
+
+Hatch manages isolated environments and dependencies automatically. The commands above use the `default` environment which is recommended for most local development.
+
+**Using the `ci` environment (optional)**
+
+If you need to replicate exactly what runs in GitHub Actions (e.g., with coverage reporting), use the `ci` environment:
+
+```sh
+cd core
+
+# Run unit tests with coverage
+hatch run ci:unit-tests
+
+# Run unit tests with a specific Python version
+hatch run +py=3.11 ci:unit-tests
+```
+
+> **Note:** Most developers should use the default environment (`hatch run unit-tests`). The `ci` environment is primarily for debugging CI failures or running tests with coverage.
 
 #### `pre-commit`
-[`pre-commit`](https://pre-commit.com) takes care of running all code-checks for formatting and linting. Run `make dev` to install `pre-commit` in your local environment (we recommend running this command with a python virtual environment active). This command installs several pip executables including black, mypy, and flake8. Once this is done you can use any of the linter-based make targets as well as a git pre-commit hook that will ensure proper formatting and linting.
 
-#### `tox`
-
-[`tox`](https://tox.readthedocs.io/en/latest/) takes care of managing virtualenvs and install dependencies in order to run tests. You can also run tests in parallel, for example, you can run unit tests for Python 3.8, Python 3.9, Python 3.10 and Python 3.11 checks in parallel with `tox -p`. Also, you can run unit tests for specific python versions with `tox -e py38`. The configuration for these tests in located in `tox.ini`.
