-### Command line options
-
-_Black_ doesn't provide many options. You can list them by running `black --help`:
-
-```text
-Usage: black [OPTIONS] [SRC]...
-
- The uncompromising code formatter.
-
-Options:
- -c, --code TEXT Format the code passed in as a string.
- -l, --line-length INTEGER How many characters per line to allow.
- [default: 88]
-
- -t, --target-version [py27|py33|py34|py35|py36|py37|py38]
- Python versions that should be supported by
- Black's output. [default: per-file auto-
- detection]
-
- --pyi Format all input files like typing stubs
- regardless of file extension (useful when
- piping source on standard input).
-
- -S, --skip-string-normalization
- Don't normalize string quotes or prefixes.
- --check Don't write the files back, just return the
- status. Return code 0 means nothing would
- change. Return code 1 means some files
- would be reformatted. Return code 123 means
- there was an internal error.
-
- --diff Don't write the files back, just output a
- diff for each file on stdout.
-
- --color / --no-color Show colored diff. Only applies when
- `--diff` is given.
-
- --fast / --safe If --fast given, skip temporary sanity
- checks. [default: --safe]
-
- --include TEXT A regular expression that matches files and
- directories that should be included on
- recursive searches. An empty value means
- all files are included regardless of the
- name. Use forward slashes for directories
- on all platforms (Windows, too). Exclusions
- are calculated first, inclusions later.
- [default: \.pyi?$]
-
- --exclude TEXT A regular expression that matches files and
- directories that should be excluded on
- recursive searches. An empty value means no
- paths are excluded. Use forward slashes for
- directories on all platforms (Windows, too).
- Exclusions are calculated first, inclusions
- later. [default: /(\.eggs|\.git|\.hg|\.mypy
- _cache|\.nox|\.tox|\.venv|\.svn|_build|buck-
- out|build|dist)/]
-
- --force-exclude TEXT Like --exclude, but files and directories
- matching this regex will be excluded even
- when they are passed explicitly as arguments
-
- -q, --quiet Don't emit non-error messages to stderr.
- Errors are still emitted; silence those with
- 2>/dev/null.
-
- -v, --verbose Also emit messages to stderr about files
- that were not changed or were ignored due to
- --exclude=.
-
- --version Show the version and exit.
- --config FILE Read configuration from PATH.
- -h, --help Show this message and exit.
-```
-
-_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).
-
-### 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.
