+yamllint
+========
+
+A linter for YAML files.
+
+yamllint does not only check for syntax validity, but for weirdnesses like key
+repetition and cosmetic problems such as lines length, trailing spaces,
+indentation, etc.

+^^^^^^^^^^
+
+.. image:: docs/screenshot.png
+   :alt: yamllint screenshot
+
+Installation
+^^^^^^^^^^^^
+
+On Fedora / CentOS:
+
+.. code:: bash
+
+ sudo dnf install yamllint
+
+On Debian 9+ / Ubuntu 16.04+:
+
+.. code:: bash
+
+ sudo apt-get install yamllint
+
+Alternatively using pip, the Python package manager:
+
+.. code:: bash
+
+ sudo pip install yamllint
+
+Usage
+^^^^^
+
+.. code:: bash
+
+ # Lint one or more files
+ yamllint my_file.yml my_other_file.yaml ...
+
+.. code:: bash
+
+ # Lint all YAML files in a directory
+ yamllint .
+
+.. code:: bash
+
+ # Use a pre-defined lint configuration
+ yamllint -d relaxed file.yaml
+
+ # Use a custom lint configuration
+ yamllint -c /path/to/myconfig file-to-lint.yaml
+
+.. code:: bash
+
+ # Output a parsable format (for syntax checking in editors like Vim, emacs...)
+ yamllint -f parsable file.yaml
+
+`Read more in the complete documentation! <http://yamllint.readthedocs.io/>`_
+
+Features
+^^^^^^^^
+
+Here is a yamllint configuration file example:
+
+.. code:: yaml
+
+ extends: default
+
+ rules:
+   # 80 chars should be enough, but don't fail if a line is longer
+   line-length:
+     max: 80
+     level: warning
+
+   # don't bother me with this rule
+   indentation: disable
+
+Within a YAML file, special comments can be used to disable checks for a single
+line:
+
+.. code:: yaml
+
+ This line is waaaaaaaaaay too long  # yamllint disable-line
+
+or for a whole block:
+
+.. code:: yaml
+
+ # yamllint disable rule:colons
+ - Lorem       : ipsum
+   dolor       : sit amet,
+   consectetur : adipiscing elit
+ # yamllint enable

+Configuration
+=============
+
+yamllint uses a set of :doc:`rules <rules>` to check source files for problems.
+Each rule is independent from the others, and can be enabled, disabled or
+tweaked. All these settings can be gathered in a configuration file.
+
+To use a custom configuration file, use the ``-c`` option:
+
+.. code:: bash
+
+ yamllint -c /path/to/myconfig file-to-lint.yaml
+
+If ``-c`` is not provided, yamllint will look for a configuration file in the
+following locations (by order of preference):
+
+- ``.yamllint`` in the current working directory
+- ``$XDG_CONFIG_HOME/yamllint/config``
+- ``~/.config/yamllint/config``
+
+Finally if no config file is found, the default configuration is applied.
+
+Default configuration
+---------------------
+
+Unless told otherwise, yamllint uses its ``default`` configuration:
+
+.. literalinclude:: ../yamllint/conf/default.yaml
+   :language: yaml
+
+Details on rules can be found on :doc:`the rules page <rules>`.
+
+There is another pre-defined configuration named ``relaxed``. As its name
+suggests, it is more tolerant.
+
+It can be chosen using:
+
+.. code:: bash
+
+ yamllint -d relaxed file.yml
+
+Extending the default configuration
+-----------------------------------
+
+When writing a custom configuration file, you don't need to redefine every rule.
+Just extend the ``default`` configuration (or any already-existing configuration
+file).
+
+For instance, if you just want to disable the ``comments-indentation`` rule,
+your file could look like this:
+
+.. code-block:: yaml
+
+ # This is my first, very own configuration file for yamllint!
+ # It extends the default conf by adjusting some options.
+
+ extends: default
+
+ rules:
+   comments-indentation: disable  # don't bother me with this rule
+
+Similarly, if you want to set the ``line-length`` rule as a warning and be less
+strict on block sequences indentation:
+
+.. code-block:: yaml
+
+ extends: default
+
+ rules:
+   # 80 chars should be enough, but don't fail if a line is longer
+   line-length:
+     max: 80
+     level: warning
+
+   # accept both     key:
+   #                   - item
+   #
+   # and             key:
+   #                 - item
+   indentation:
+     indent-sequences: whatever
+
+Custom configuration without a config file
+------------------------------------------
+
+It is possible -- although not recommended -- to pass custom configuration
+options to yamllint with the ``-d`` (short for ``--config-data``) option.
+
+Its content can either be the name of a pre-defined conf (example: ``default``
+or ``relaxed``) or a serialized YAML object describing the configuration.
+
+For instance:
+
+.. code:: bash
+
+ yamllint -d "{extends: relaxed, rules: {line-length: {max: 120}}}" file.yaml
+
+Errors and warnings
+-------------------
+
+Problems detected by yamllint can be raised either as errors or as warnings.
+
+In both cases, the script will output them (with different colors when using the
+``standard`` output format), but the exit code can be different. More precisely,
+the script will exit will a failure code *only when* there is one or more
+error(s).

+Disable with comments
+=====================
+
+Disabling checks for a specific line
+------------------------------------
+
+To prevent yamllint from reporting problems for a specific line, add a directive
+comment (``# yamllint disable-line ...``) on that line, or on the line above.
+For instance:
+
+.. code-block:: yaml
+
+ # The following mapping contains the same key twice,
+ # but I know what I'm doing:
+ key: value 1
+ key: value 2  # yamllint disable-line rule:key-duplicates
+
+ - This line is waaaaaaaaaay too long but yamllint will not report anything about it.  # yamllint disable-line rule:line-length
+   This line will be checked by yamllint.
+
+or:
+
+.. code-block:: yaml
+
+ # The following mapping contains the same key twice,
+ # but I know what I'm doing:
+ key: value 1
+ # yamllint disable-line rule:key-duplicates
+ key: value 2
+
+ # yamllint disable-line rule:line-length
+ - This line is waaaaaaaaaay too long but yamllint will not report anything about it.
+   This line will be checked by yamllint.
+
+It it possible, although not recommend, to disabled **all** rules for a
+specific line:
+
+.. code-block:: yaml
+
+ # yamllint disable-line
+ -  {    all : rules ,are disabled   for this line}
+
+If you need to disable multiple rules, it is allowed to chain rules like this:
+``# yamllint disable-line rule:hyphens rule:commas rule:indentation``.
+
+Disabling checks for all (or part of) the file
+----------------------------------------------
+
+To prevent yamllint from reporting problems for the whoe file, or for a block of
+lines within the file, use ``# yamllint disable ...`` and ``# yamllint enable
+...`` directive comments. For instance:
+
+.. code-block:: yaml
+
+ # yamllint disable rule:colons
+ - Lorem       : ipsum
+   dolor       : sit amet,
+   consectetur : adipiscing elit
+ # yamllint enable rule:colons
+
+ - rest of the document...
+
+It it possible, although not recommend, to disabled **all** rules:

+ - Lorem       :
+         ipsum:
+           dolor : [   sit,amet]
+ -         consectetur : adipiscing elit
+ # yamllint enable
+
+If you need to disable multiple rules, it is allowed to chain rules like this:

+Quickstart
+==========
+
+Installing yamllint
+-------------------
+
+On Fedora / CentOS:
+
+.. code:: bash
+
+ sudo dnf install yamllint
+
+On Debian 9+ / Ubuntu 16.04+:
+
+.. code:: bash
+
+ sudo apt-get install yamllint
+
+On older Debian / Ubuntu versions:
+
+.. code:: bash
+
+ sudo add-apt-repository -y ppa:adrienverge/ppa && sudo apt-get update
+ sudo apt-get install yamllint
+
+Alternatively using pip, the Python package manager:
+
+.. code:: bash
+
+ sudo pip install yamllint
+
+If you prefer installing from source, you can run, from the source directory:
+
+.. code:: bash
+
+ python setup.py sdist
+ sudo pip install dist/yamllint-*.tar.gz
+
+Running yamllint
+----------------
+
+Basic usage:
+
+.. code:: bash
+
+ yamllint file.yml other-file.yaml
+
+You can also lint all YAML files in a whole directory:
+
+.. code:: bash
+
+ yamllint .
+
+The output will look like (colors are not displayed here):
+
+::
+
+ file.yml
+   1:4       error    trailing spaces  (trailing-spaces)
+   4:4       error    wrong indentation: expected 4 but found 3  (indentation)
+   5:4       error    duplication of key "id-00042" in mapping  (key-duplicates)
+   6:6       warning  comment not indented like content  (comments-indentation)
+   12:6      error    too many spaces after hyphen  (hyphens)
+   15:12     error    too many spaces before comma  (commas)
+
+ other-file.yaml
+   1:1       warning  missing document start "---"  (document-start)
+   6:81      error    line too long (87 > 80 characters)  (line-length)
+   10:1      error    too many blank lines (4 > 2)  (empty-lines)
+   11:4      error    too many spaces inside braces  (braces)
+
+Add the ``-f parsable`` arguments if you need an output format parsable by a
+machine (for instance for :doc:`syntax highlighting in text editors
+<text_editors>`). The output will then look like:
+
+::
+
+ file.yml:6:2: [warning] missing starting space in comment (comments)
+ file.yml:57:1: [error] trailing spaces (trailing-spaces)
+ file.yml:60:3: [error] wrong indentation: expected 4 but found 2 (indentation)
+
+If you have a custom linting configuration file (see :doc:`how to configure
+yamllint <configuration>`), it can be passed to yamllint using the ``-c``
+option:
+
+.. code:: bash
+
+ yamllint -c ~/myconfig file.yaml
+
+.. note::
+
+   If you have a ``.yamllint`` file in your working directory, it will be
+   automatically loaded as configuration by yamllint.

+Rules
+=====
+
+When linting a document with yamllint, a series of rules (such as
+``line-length``, ``trailing-spaces``, etc.) are checked against.
+
+A :doc:`configuration file <configuration>` can be used to enable or disable
+these rules, to set their level (*error* or *warning*), but also to tweak their
+options.

+Integration with text editors
+=============================
+
+Most text editors support syntax checking and highlighting, to visually report
+syntax errors and warnings to the user. yamllint can be used to syntax-check
+YAML source, but a bit of configuration is required depending on your favorite
+text editor.
+
+Vim
+---
+
+Assuming that the `syntastic <https://github.com/scrooloose/syntastic>`_ plugin
+is installed, add to your ``.vimrc``:
+
+::
+
+ let g:syntastic_yaml_checkers = ['yamllint']
+
+Neovim
+------
+
+Assuming that the `neomake <https://github.com/benekastah/neomake>`_ plugin is
+installed, yamllint is supported by default. It is automatically enabled when
+editing YAML files.
+
+Other text editors
+------------------
+
+.. rubric:: Help wanted!
+
+Your favorite text editor is not listed here? Help us improve by adding a
+section (by opening a pull-request or issue on GitHub).
