+This section introduces a guide lines for writing idiomatic, robust and future-proof extractor code.
 
 Extractors are very fragile by nature since they depend on the layout of the source data provided by 3rd party media hosters out of your control and this layout tends to change. As an extractor implementer your task is not only to write code that will extract media links and metadata correctly but also to minimize dependency on the source's layout and even to make the code foresee potential future changes and be ready for that. This is important because it will allow the extractor not to break on minor layout changes thus keeping old youtube-dl versions working. Even though this breakage issue is easily fixed by emitting a new version of youtube-dl with a fix incorporated, all the previous versions become broken in all repositories and distros' packages that may not be so prompt in fetching the update from us. Needless to say, some non rolling release distros may never receive an update at all.

 #### More examples
 
 ##### Safely extract optional description from parsed JSON
-
-When processing complex JSON, as often returned by site API requests or stashed in web pages for "hydration", you can use the `traverse_obj()` utility function to handle multiple fallback values and to ensure the expected type of metadata items. The function's docstring defines how the function works: also review usage in the codebase for more examples.
-
-In this example, a text `description`, or `None`, is pulled from the `.result.video[0].summary` member of the parsed JSON `response`, if available.
-
-```python
-description = traverse_obj(response, ('result', 'video', 0, 'summary', T(compat_str)))
-```
-`T(...)` is a shorthand for a set literal; if you hate people who still run Python 2.6, `T(type_or_transformation)` could be written as a set literal `{type_or_transformation}`.
-
-Some extractors use the older and less capable `try_get()` function in the same way.
-
 ```python
 description = try_get(response, lambda x: x['result']['video'][0]['summary'], compat_str)
 ```
 
 ##### Safely extract more optional metadata
-
-In this example, various optional metadata values are extracted from the `.result.video[0]` member of the parsed JSON `response`, which is expected to be a JS object, parsed into a `dict`, with no crash if that isn't so, or if any of the target values are missing or invalid.
-
 ```python
-video = traverse_obj(response, ('result', 'video', 0, T(dict))) or {}
-# formerly:
-# video = try_get(response, lambda x: x['result']['video'][0], dict) or {}
+video = try_get(response, lambda x: x['result']['video'][0], dict) or {}
 description = video.get('summary')
 duration = float_or_none(video.get('durationMs'), scale=1000)
 view_count = int_or_none(video.get('views'))
 ```
 
-#### Safely extract nested lists
-
-Suppose you've extracted JSON like this into a Python data structure named `media_json` using, say, the `_download_json()` or `_parse_json()` methods of `InfoExtractor`:
-```json
-{
-    "title": "Example video",
-    "comment": "try extracting this",
-    "media": [{
-        "type": "bad",
-        "size": 320,
-        "url": "https://some.cdn.site/bad.mp4"
-    }, {
-        "type": "streaming",
-        "url": "https://some.cdn.site/hls.m3u8"
-    }, {
-        "type": "super",
-        "size": 1280,
-        "url": "https://some.cdn.site/good.webm"
-    }],
-    "moreStuff": "more values",
-    ...
-}
-```
-
-Then extractor code like this can collect the various fields of the JSON:
-```python
-...
-from ..utils import (
-    determine_ext,
-    int_or_none,
-    T,
-    traverse_obj,
-    txt_or_none,
-    url_or_none,
-)
-...
-        ...
-        info_dict = {}
-        # extract title and description if valid and not empty
-        info_dict.update(traverse_obj(media_json, {
-            'title': ('title', T(txt_or_none)),
-            'description': ('comment', T(txt_or_none)),
-        }))
-
-        # extract any recognisable media formats
-        fmts = []
-        # traverse into "media" list, extract `dict`s with desired keys
-        for fmt in traverse_obj(media_json, ('media', Ellipsis, {
-                'format_id': ('type', T(txt_or_none)),
-                'url': ('url', T(url_or_none)),
-                'width': ('size', T(int_or_none)), })):
-            # bad `fmt` values were `None` and removed
-            if 'url' not in fmt:
-                continue
-            fmt_url = fmt['url']  # known to be valid URL
-            ext = determine_ext(fmt_url)
-            if ext == 'm3u8':
-                fmts.extend(self._extract_m3u8_formats(fmt_url, video_id, 'mp4', fatal=False))
-            else:
-                fmt['ext'] = ext
-                fmts.append(fmt)
-
-        # sort, raise if no formats
-        self._sort_formats(fmts)
-
-        info_dict['formats'] = fmts
-        ...
-```
-The extractor raises an exception rather than random crashes if the JSON structure changes so that no formats are found.

-    A subclass of InfoExtractor must be defined to handle each specific site (or
-    several sites). Such a concrete subclass should be added to the list of
-    extractors. It should also:
-    * define its _VALID_URL attribute as a regexp, or a Sequence of alternative
-      regexps (but see below)
-    * re-define the _real_extract() method
-    * optionally re-define the _real_initialize() method.
-
-    An extractor subclass may also override suitable() if necessary, but the
-    function signature must be preserved and the function must import everything
-    it needs (except other extractors), so that lazy_extractors works correctly.
-    If the subclass's suitable() and _real_extract() functions avoid using
-    _VALID_URL, the subclass need not set that class attribute.
-
-    An abstract subclass of InfoExtractor may be used to simplify implementation
-    within an extractor module; it should not be added to the list of extractors.
+    Subclasses of this one should re-define the _real_initialize() and

+    Probably, they should also be added to the list of extractors.
