+    'This is a <c.colorE5E5E5>caption</c> text'
+
+    # caption identifiers
+    >>> vtt[0].identifier
+    'chapter 1'
+
+
+Reading WebVTT caption files from a file-like object
+----------------------------------------------------
+
+.. code-block:: python
+
+    import webvtt
+    import requests
+    from io import StringIO
+
+    payload = requests.get('http://subtitles.com/1234.vtt').text()

+
+
+Reading WebVTT captions from a string
+-------------------------------------
+
+.. code-block:: python
+
+    import webvtt
+    import textwrap
+
+    vtt = webvtt.from_string(textwrap.dedent("""

+
+
+Iterate a slice of captions
+---------------------------
+
+.. code-block:: python

+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+    for caption in vtt.iter_slice(start='00:00:11.000',

+        print(caption.start)
+        print(caption.end)
+        print(caption.text)
+
+
+Creating captions
+-----------------
+
+.. code-block:: python
+
+    from webvtt import WebVTT, Caption
+
+    vtt = WebVTT()
+
+    # creating a caption with a list of lines
+    caption = Caption(
+        '00:00:00.500',
+        '00:00:07.000',
+        ['Caption line 1', 'Caption line 2']
+    )
+
+    # an identifier can be assigned
+    caption.identifier = 'chapter 1'
+
+    # adding a caption
+    vtt.captions.append(caption)
+
+    # creating another caption with a text
+    caption = Caption(
+        '00:00:07.000',
+        '00:00:11.890',
+        'Caption line 1\nCaption line 2'
+    )
+
+    vtt.captions.append(caption)
+
+
+Manipulating captions
+---------------------
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    # update start timestamp
+    vtt[0].start = '00:00:01.250'
+
+    # update end timestamp
+    vtt[0].end = '00:00:03.890'
+
+    # update caption text
+    vtt[0].text = 'New caption text'
+
+    # delete a caption
+    del vtt.captions[2]
+
+
+Saving captions
+---------------
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    # save to the same file
+    vtt.save()
+
+    # save to a different file
+    vtt.save('new_captions.vtt')
+
+    # you can save to a file path
+    vtt.save('other/folder/new_captions')
+
+    # if there is a filename present in the object we can target a folder
+    vtt.save('other/folder)
+
+    # write to an opened file
+    with open('other_captions.vtt', 'w') as f:
+        vtt.write(f)
+
+
+Retrieving WebVTT formatted captions
+------------------------------------
+
+WebVTT content can be retrieved without an output file:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    # print the content in WebVTT format
+    print(vtt.content)
+
+
+Converting captions
+-------------------
+
+You can read captions from the following formats:
+
+* SubRip (.srt)
+* YouTube SBV (.sbv)
+
+.. code-block:: python
+
+    import webvtt
+
+    # read captions from SRT format
+    vtt = webvtt.from_srt('captions.srt')
+
+    # save the captions in WebVTT format
+    vtt.save()
+
+    # the conversion can be done chaining the method calls
+    webvtt.from_srt('captions.srt').save()
+
+    # the same for SBV format
+    vtt = webvtt.from_sbv('captions.sbv')
+
+Convert WebVTT captions to other formats:
+
+* SubRip (.srt)
+
+.. code-block:: python
+
+    import webvtt
+
+    # save in SRT format
+    vtt = webvtt.read('captions.vtt')
+    vtt.save_as_srt()
+
+    # write to an opened file in SRT format
+    with open('captions.srt', 'w') as f:
+        vtt.write(f, format='srt')
+
+
+WebVTT files with Byte Order Mark (BOM)
+---------------------------------------
+
+When the WebVTT file has BOM, saving it will keep the BOM:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions_with_bom.vtt')
+
+    # saved file keeps the BOM
+    vtt.save()
+
+
+Add a BOM to a file without it:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions_without_bom.vtt',
+                      add_bom=True
+                      )
+
+    # saved file has BOM
+    vtt.save()
+
+
+Remove the BOM from a file:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions_with_bom.vtt')
+
+    # saved file does not have BOM
+    vtt.save(add_bom=False)
+
+
+Save file with a different encoding:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    vtt.save(encoding='utf-32-le')
+
+    # save in different encoding with BOM
+    vtt.save(encoding='utf-32-le',
+             add_bom=True
+             )
+
+
+
+WebVTT Styles
+-------------
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    for style in vtt.styles:
+        print(style.text)
+
+        # retrieve list of lines
+        print(style.lines)
+
+
+Adding styles:
+
+.. code-block:: python
+
+    import webvtt
+
+    vtt = webvtt.read('captions.vtt')
+
+    vtt.styles.append(
+        webvtt.Style('::cue(b) {\n  color: peachpuff;\n}')
+        )
+    # list of lines is supported

-Usage
-=====
-
-Reading WebVTT caption files
-----------------------------
-
-.. code-block:: python
-
-    import webvtt
-
-    # we can iterate over the captions
-    for caption in webvtt.read('captions.vtt'):
-        print(caption.start)  # start timestamp in text format
-        print(caption.end)  # end timestamp in text format
-        print(caption.text)  # caption text
-
-    # you can also iterate over the lines of a particular caption
-    for line in vtt[0].lines:
-        print(line)
-
-    # caption text is returned clean without class tags
-    # we can access the raw text of a caption with raw_text
-    >>> vtt[0].text
-    'This is a caption text'
-    >>> vtt[0].raw_text
-    'This is a <c.colorE5E5E5>caption</c> text'
-
-    # caption identifiers
-    >>> vtt[0].identifier
-    'crédit de transcription'
-
-
-Reading WebVTT caption files from file-like object
---------------------------------------------------
-
-.. code-block:: python
-
-    import webvtt
-    import requests
-    from io import StringIO
-
-    payload = requests.get('http://subtitles.com/1234.vtt').text()
-    buffer = StringIO(payload)
-
-    for caption in webvtt.read_buffer(buffer):
-        print(caption.start)
-        print(caption.end)
-        print(caption.text)
-
-
-Creating captions
------------------
-
-.. code-block:: python
-
-    from webvtt import WebVTT, Caption
-
-    vtt = WebVTT()
-
-    # creating a caption with a list of lines
-    caption = Caption(
-        '00:00:00.500',
-        '00:00:07.000',
-        ['Caption line 1', 'Caption line 2']
-    )
-
-    # adding a caption
-    vtt.captions.append(caption)
-
-    # creating another caption with a text
-    caption = Caption(
-        '00:00:07.000',
-        '00:00:11.890',
-        'Caption line 1\nCaption line 2'
-    )
-
-    vtt.captions.append(caption)
-
-
-Manipulating captions
----------------------
-
-.. code-block:: python
-
-    import webvtt
-
-    vtt = webvtt.read('captions.vtt')
-
-    # update start timestamp
-    vtt[0].start = '00:00:01.250'
-
-    # update end timestamp
-    vtt[0].end = '00:00:03.890'
-
-    # update caption text
-    vtt[0].text = 'My caption text'
-
-    # delete a caption
-    del vtt.captions[2]
-
-
-Saving captions
----------------
-
-.. code-block:: python
-
-    import webvtt
-
-    vtt = webvtt.read('captions.vtt')
-
-    # save to original file
-    vtt.save()
-
-    # save to a different file
-    vtt.save('my_captions.vtt')
-
-    # write to opened file
-    with open('my_captions.vtt', 'w') as fd:
-        vtt.write(fd)
-
-
-Fetching WebVTT formatted Captions
-------------------------------------
-
-WebVTT formatted captions content can be obtained without having to create an output file.
-
-.. code-block:: python
-
-    import webvtt
-
-    vtt = webvtt.read('captions.vtt')
-
-    # Print the captions formatted in webvtt
-    print(vtt.content)
-
-
-Converting captions
--------------------
-
-You can read captions from the following formats:
-
-* SubRip (.srt)
-* YouTube SBV (.sbv)
-
-.. code-block:: python
-
-    import webvtt
-
-    # to read from a different format use the method from_ followed by
-    # the extension.
-    vtt = webvtt.from_sbv('captions.sbv')
-    vtt.save()
-
-    # if we just want to convert the file we can do this in one line
-    webvtt.from_sbv('captions.sbv').save()
-
-Also we can convert WebVTT to other formats:
-
-* SubRip (.srt)
-
-.. code-block:: python
-
-    import webvtt
-
-    # save in SRT format
-    vtt = webvtt.read('captions.vtt')
-    vtt.save_as_srt()
-
-    # write to opened file in SRT format
-    with open('my_captions.srt', 'w') as fd:
-        vtt.write(fd, format='srt')
