+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

+ 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
