 ## Custom configuration
 
-### Standard
-
-By default, the twig-cs-fixer standard is enabled with the twig coding standard rules and the following rules:
-
- - `BlankEOFRule`: ensures that files end with one blank line.
- - `BlockNameSpacingRule`: ensure there is one space before and after block names.
- - `EmptyLinesRule`: ensures that 2 empty lines do not follow each other.
- - `IndentRule`: ensures that files are not indented with tabs.
- - `TrailingCommaSingleLineRule`: ensures that single-line arrays, objects and argument lists do not have a trailing comma.
- - `TrailingSpaceRule`: ensures that files have no trailing spaces.
-
-If you want to use the basic Twig standard, another standard and/or add/disable a rule, you can provide
-your own configuration with a `.twig-cs-fixer.php` file which returns a `TwigCsFixer\Config\Config` class:
-
-```php
-<?php
-
-$ruleset = new TwigCsFixer\Ruleset\Ruleset();
-$ruleset->addStandard(new TwigCsFixer\Standard\Twig());
-$ruleset->addRule(\TwigCsFixer\Rules\Whitespace\EmptyLinesRule::class);
-
-$config = new TwigCsFixer\Config\Config();
-$config->setRuleset($ruleset);
-
-return $config;
-```
-
-If your config is not located in your current directory, you can specify its path using `--config` when running the command:
-
-```bash
-vendor/bin/twig-cs-fixer lint --config=dir/.twig-cs-fixer.php /path/to/code
-```
-
-### Files
-
-By default, all `.twig` files in the current directory are linted, except the ones in the `vendor` directory.
-
-If you want to lint specific files or directories you can pass them as argument. If you want a more sophisticated
-rule, you can configure it in the `.twig-cs-fixer.php` file:
-
-```php
-<?php
-
-$finder = new TwigCsFixer\File\Finder();
-$finder->exclude('myCustomDirectory');
-
-$config = new TwigCsFixer\Config\Config();
-$config->setFinder($finder);
-
-return $config;
-```
-
-### Cache
-
-By default, cache is enabled and stored in `.twig-cs-fixer.cache`. Further runs are therefore much
-faster. Cache is invalidated when a different PHP version, twig-cs-fixer version or ruleset is used.
-
-If you want a custom cache location you can configure it in `.twig-cs-fixer.php`:
-
-```php
-<?php
-
-$config = new TwigCsFixer\Config\Config();
-$config->setCacheFile('/tmp/.twig-cs-fixer.cache');
-
-return $config;
-```
-
-To disable cache you can either pass `--no-cache` when running the command:
-
-```bash
-vendor/bin/twig-cs-fixer lint --no-cache
-```
-
-or set the cache file to `null` in your config:
-
-```php
-<?php
-
-$config = new TwigCsFixer\Config\Config();
-$config->setCacheFile(null);
-
-return $config;
-```
-
-### Token parser
-
-If you're using custom token parsers or binary/unary operators, they can be added in your config:
-
-```php
-<?php
-
-$config = new TwigCsFixer\Config\Config();
-$config->addTwigExtension(new App\Twig\CustomTwigExtension());
-$config->addTokenParser(new App\Twig\CustomTokenParser());
-
-return $config;
-```
-
-### Reporter
-
-The `--report` option allows to choose the output format for the linter report.
-
-Supported formats are:
-- `text` selected by default.
-- `checkstyle` following the common checkstyle XML schema.
-- `github` if you want annotations on GitHub actions.
-- `junit` following JUnit schema XML from Jenkins.
-- `null` if you don't want any reporting.

+# How to disable a rule on a specific file or line
+
+All errors have an identifier with the syntax: `A.B:C:D` with
+- A: The rule short name (mainly made from the class name)
+- B: The error identifier (like the error level or a specific name)
+- C: The line the error occurs
+- D: The position of the token in the line the error occurs
+
+NB: The four parts are optional, all those format are working
+- A
+- A.B
+- A.B:C
+- A.B:C:D
+- A:C
+- A:C:D
+- A::D
+
+When you want to disable a rule, you can use of the following syntax:
+```twig
+{# twig-cs-fixer-disable A.B:C:D #} => Apply to the whole file
+{# twig-cs-fixer-disable-line A.B:C:D #} => Apply to the line of the comment
+{# twig-cs-fixer-disable-next-line A.B:C:D #} => Apply to the next line of the comment
+```
+
+For instance:
+```twig
+{# twig-cs-fixer-disable #} => Disable every rule for the whole file
+{# twig-cs-fixer-disable-line #} => Disable every rule for the current line
+{# twig-cs-fixer-disable-next-line #} => Disable every rule for the next line
+
+{# twig-cs-fixer-disable A #} => Disable the rule A for the whole file
+{# twig-cs-fixer-disable A:42 #} => Disable the rule A for the line 42 of the file
+{# twig-cs-fixer-disable-line A.B #} => Disable the error B of the rule A for the current line
+{# twig-cs-fixer-disable-next-line A::42 #} => Disable the rule A for the next line but only for the token 42
+```
+
+You can also disable multiple errors with a single comment, by separating them
+with a space or a comma:
+```twig
+{# twig-cs-fixer-disable A B C #} => Disable A and B and C for the whole file
+{# twig-cs-fixer-disable-line A.B,C.D #} => Disable A.B and C.D for the current line
+```
+
+If you need to know the errors identifier you have/want to ignore, you can run the 
+linter command with the `--debug` options. See also [the command options](command.md).
