## Bird's eye view
-In terms of inspiration, *Black* is about as configurable as *gofmt* and
-*rustfmt* are. This is deliberate.
-
-Bug reports and fixes are always welcome! Please follow the issue
-template on GitHub for best results.

-Before you suggest a new feature or configuration knob, ask yourself why
-you want it. If it enables better integration with some workflow, fixes
-an inconsistency, speeds things up, and so on - go for it! On the other
-hand, if your answer is "because I don't like a particular formatting"
-then you're not ready to embrace *Black* yet. Such changes are unlikely
-to get accepted. You can still try but prepare to be disappointed.

## Technicalities
-Development on the latest version of Python is preferred. As of this
-writing it's 3.6.4. You can use any operating system. I am using macOS
-myself and CentOS at work.

Install all development dependencies using:
+
```
$ pipenv install --dev
+$ pipenv shell
+$ pre-commit install
```
-If you haven't used `pipenv` before but are comfortable with virtualenvs,
-just run `pip install pipenv` in the virtualenv you're already using and
-invoke the command above from the cloned Black repo. It will do the
-correct thing.

Before submitting pull requests, run tests with:
+
```
$ python setup.py test
```
-Also run mypy and flake8 on `black.py` and `test_black.py`. Travis will
-run all that for you but if you left any errors here, it will be quicker
-and less embarrassing to fix them locally ;-)

## Hygiene
-If you're fixing a bug, add a test. Run it first to confirm it fails,
-then fix the bug, run it again to confirm it's really fixed.
-
-If adding a new feature, add a test. In fact, always add a test. But
-wait, before adding any large feature, first open an issue for us to
-discuss the idea first.

## Finally
-Thanks again for your interest in improving the project! You're taking
-action when most people decide to sit and watch.
