-_Black_ is a well-behaved Unix-style command-line tool:
-
-- it does nothing if no sources are passed to it;
-- it will read from standard input and write to standard output if `-` is used as the
-  filename;
-- it only outputs messages to users on standard error;
-- exits with code 0 unless an internal error occurred (or `--check` was used).
-
-### Using _Black_ with other tools
-
-While _Black_ enforces formatting that conforms to PEP 8, other tools may raise warnings
-about _Black_'s changes or will overwrite _Black_'s changes. A good example of this is
-[isort](https://pypi.org/p/isort). Since _Black_ is barely configurable, these tools
-should be configured to neither warn about nor overwrite _Black_'s changes.
-
-Actual details on _Black_ compatible configurations for various tools can be found in
-[compatible_configs](https://github.com/psf/black/blob/master/docs/compatible_configs.md#black-compatible-configurations).
-
-### Migrating your code style without ruining git blame
-
-A long-standing argument against moving to automated code formatters like _Black_ is
-that the migration will clutter up the output of `git blame`. This was a valid argument,
-but since Git version 2.23, Git natively supports
-[ignoring revisions in blame](https://git-scm.com/docs/git-blame#Documentation/git-blame.txt---ignore-revltrevgt)
-with the `--ignore-rev` option. You can also pass a file listing the revisions to ignore
-using the `--ignore-revs-file` option. The changes made by the revision will be ignored
-when assigning blame. Lines modified by an ignored revision will be blamed on the
-previous revision that modified those lines.
-
-So when migrating your project's code style to _Black_, reformat everything and commit
-the changes (preferably in one massive commit). Then put the full 40 characters commit
-identifier(s) into a file.
-
-```
-# Migrate code style to Black
-5b4ab991dede475d393e9d69ec388fd6bd949699
-```
-
-Afterwards, you can pass that file to `git blame` and see clean and meaningful blame
-information.
-
-```console
-$ git blame important.py --ignore-revs-file .git-blame-ignore-revs
-7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 1) def very_important_function(text, file):
-abdfd8b0 (Alice Doe  2019-09-23 11:39:32 -0400 2)     text = text.lstrip()
-7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 3)     with open(file, "r+") as f:
-7a1ae265 (John Smith 2019-04-15 15:55:13 -0400 4)         f.write(formatted)
-```
-
-You can even configure `git` to automatically ignore revisions listed in a file on every
-call to `git blame`.
-
-```console
-$ git config blame.ignoreRevsFile .git-blame-ignore-revs
-```
+Further information can be found in our docs:

 
 

-**The one caveat is that GitHub and GitLab do not yet support ignoring revisions using
-their native UI of blame.** So blame information will be cluttered with a reformatting
-commit on those platforms. (If you'd like this feature, there's an open issue for
-[GitLab](https://gitlab.com/gitlab-org/gitlab/-/issues/31423) and please let GitHub
-know!)

 _Black_ is able to read project-specific default values for its command line options
 from a `pyproject.toml` file. This is especially useful for specifying custom

-`--include` and `--exclude`/`--extend-exclude` patterns for your project.
-
-**Pro-tip**: If you're asking yourself "Do I need to configure anything?" the answer is
-"No". _Black_ is all about sensible defaults.
-
-### What on Earth is a `pyproject.toml` file?
-
-[PEP 518](https://www.python.org/dev/peps/pep-0518/) defines `pyproject.toml` as a
-configuration file to store build system requirements for Python projects. With the help
-of tools like [Poetry](https://python-poetry.org/) or
-[Flit](https://flit.readthedocs.io/en/latest/) it can fully replace the need for
-`setup.py` and `setup.cfg` files.
-
-### Where _Black_ looks for the file
-
-By default _Black_ looks for `pyproject.toml` starting from the common base directory of
-all files and directories passed on the command line. If it's not there, it looks in
-parent directories. It stops looking when it finds the file, or a `.git` directory, or a
-`.hg` directory, or the root of the file system, whichever comes first.
-
-If you're formatting standard input, _Black_ will look for configuration starting from
-the current working directory.
-
-You can also explicitly specify the path to a particular file that you want with
-`--config`. In this situation _Black_ will not look for any other file.
-
-If you're running with `--verbose`, you will see a blue message if a file was found and
-used.
-
-Please note `blackd` will not use `pyproject.toml` configuration.
-
-### Configuration format
-
-As the file extension suggests, `pyproject.toml` is a
-[TOML](https://github.com/toml-lang/toml) file. It contains separate sections for
-different tools. _Black_ is using the `[tool.black]` section. The option keys are the
-same as long names of options on the command line.
-
-Note that you have to use single-quoted strings in TOML for regular expressions. It's
-the equivalent of r-strings in Python. Multiline strings are treated as verbose regular
-expressions by Black. Use `[ ]` to denote a significant space character.
-
-<details>
-<summary>Example <code>pyproject.toml</code></summary>
-
-```toml
-[tool.black]
-line-length = 88
-target-version = ['py37']
-include = '\.pyi?$'
-extend-exclude = '''
-# A regex preceded with ^/ will apply only to files and directories
-# in the root of the project.
-^/foo.py  # exclude a file named foo.py in the root of the project (in addition to the defaults)
-'''
-```
-
-</details>
-
-### Lookup hierarchy
-
-Command-line options have defaults that you can see in `--help`. A `pyproject.toml` can
-override those defaults. Finally, options provided by the user on the command line
-override both.
-
-_Black_ will only ever use one `pyproject.toml` file during an entire run. It doesn't
-look for multiple files, and doesn't compose configuration from different levels of the
-file hierarchy.
-
-## Editor integration
-
-_Black_ can be integrated into many editors with plugins. They let you run _Black_ on
-your code with the ease of doing it in your editor. To get started using _Black_ in your
-editor of choice, please see
-[editor_integration](https://github.com/psf/black/blob/master/docs/editor_integration.md).
-
-Patches are welcome for editors without an editor integration or plugin! More
-information can be found in
-[editor_integration](https://github.com/psf/black/blob/master/docs/editor_integration.md#other-editors).
-
-## blackd
-
-`blackd` is a small HTTP server that exposes Black's functionality over a simple
-protocol. The main benefit of using it is to avoid paying the cost of starting up a new
-Black process every time you want to blacken a file. Please refer to

-## black-primer
-
-`black-primer` is a tool built for CI (and humans) to have _Black_ `--check` a number of
-(configured in `primer.json`) Git accessible projects in parallel.
-[black_primer](https://github.com/psf/black/blob/master/docs/black_primer.md) has more
-information regarding its usage and configuration.
-
-(A PR adding Mercurial support will be accepted.)
-
-## Version control integration
-
-Use [pre-commit](https://pre-commit.com/). Once you
-[have it installed](https://pre-commit.com/#install), add this to the
-`.pre-commit-config.yaml` in your repository:
-
-```yaml
-repos:
-  - repo: https://github.com/psf/black
-    rev: 20.8b1 # Replace by any tag/version: https://github.com/psf/black/tags
-    hooks:
-      - id: black
-        language_version: python3 # Should be a command that runs python3.6+
-```
-
-Then run `pre-commit install` and you're ready to go.
-
-Avoid using `args` in the hook. Instead, store necessary configuration in
-`pyproject.toml` so that editors and command-line usage of Black all behave consistently
-for your project. See _Black_'s own
-[pyproject.toml](https://github.com/psf/black/blob/master/pyproject.toml) for an
-example.
+`--include` and `--exclude`/`--force-exclude`/`--extend-exclude` patterns for your
+project.

 
 

-If you're already using Python 3.7, switch the `language_version` accordingly. Finally,
-`stable` is a branch that tracks the latest release on PyPI. If you'd rather run on
-master, this is also an option.
+You can find more details in our documentation:

 
 

-## GitHub Actions
+- [The basics: Configuration via a file](https://black.readthedocs.io/en/stable/usage_and_configuration/the_basics.html#configuration-via-a-file)

+And if you're looking for more general configuration documentation:

-      - uses: actions/setup-python@v2
-      - uses: psf/black@stable
-        with:
-          args: ". --check"
-```
-
-### Inputs
-
-#### `black_args`
-
-**optional**: Black input arguments. Defaults to `. --check --diff`.
-
-## Ignoring unmodified files
-
-_Black_ remembers files it has already formatted, unless the `--diff` flag is used or
-code is passed via standard input. This information is stored per-user. The exact
-location of the file depends on the _Black_ version and the system on which _Black_ is
-run. The file is non-portable. The standard location on common operating systems is:
-
-- Windows:
-  `C:\\Users\<username>\AppData\Local\black\black\Cache\<version>\cache.<line-length>.<file-mode>.pickle`
-- macOS:
-  `/Users/<username>/Library/Caches/black/<version>/cache.<line-length>.<file-mode>.pickle`
-- Linux:
-  `/home/<username>/.cache/black/<version>/cache.<line-length>.<file-mode>.pickle`
-
-`file-mode` is an int flag that determines whether the file was formatted as 3.6+ only,
-as .pyi, and whether string normalization was omitted.
-
-To override the location of these files on macOS or Linux, set the environment variable
-`XDG_CACHE_HOME` to your preferred location. For example, if you want to put the cache
-in the directory you're running _Black_ from, set `XDG_CACHE_HOME=.cache`. _Black_ will
-then write the above files to `.cache/black/<version>/`.
+**Pro-tip**: If you're asking yourself "Do I need to configure anything?" the answer is
+"No". _Black_ is all about sensible defaults. Applying those defaults will have your
+code in compliance with many other _Black_ formatted projects.

-In terms of inspiration, _Black_ is about as configurable as _gofmt_. This is
-deliberate.
+Welcome! Happy to see you willing to make the project better. You can get started by
+reading this:

 
 

-Bug reports and fixes are always welcome! However, 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.

+## Code of Conduct
+
+Everyone participating in the _Black_ project, and in particular in the issue tracker,
+pull requests, and social media activity, is expected to treat other people with respect
+and more generally to follow the guidelines articulated in the
+[Python Community Code of Conduct](https://www.python.org/psf/codeofconduct/).
+
+At the same time, humor is encouraged. In fact, basic familiarity with Monty Python's
+Flying Circus is expected. We are not savages.
+
+And if you _really_ need to slap somebody, do it with a fish while dancing.
