+.SS How do I update youtube\-dl?
+.PP
+If you\[aq]ve followed our manual installation
+instructions (http://rg3.github.io/youtube-dl/download.html), you can
+simply run \f[C]youtube\-dl\ \-U\f[] (or, on Linux,
+\f[C]sudo\ youtube\-dl\ \-U\f[]).
+.PP
+If you have used pip, a simple
+\f[C]sudo\ pip\ install\ \-U\ youtube\-dl\f[] is sufficient to update.
+.PP
+If you have installed youtube\-dl using a package manager like
+\f[I]apt\-get\f[] or \f[I]yum\f[], use the standard system update
+mechanism to update.
+Note that distribution packages are often outdated.
+As a rule of thumb, youtube\-dl releases at least once a month, and
+often weekly or even daily.
+Simply go to http://yt\-dl.org/ to find out the current version.
+Unfortunately, there is nothing we youtube\-dl developers can do if your
+distributions serves a really outdated version.
+You can (and should) complain to your distribution in their bugtracker
+or support forum.
+.PP
+As a last resort, you can also uninstall the version installed by your
+package manager and follow our manual installation instructions.
+For that, remove the distribution\[aq]s package, with a line like
+.IP
+.nf
+\f[C]
+sudo\ apt\-get\ remove\ \-y\ youtube\-dl

+\f[C]Unable\ to\ extract\ OpenGraph\ title\f[] on YouTube playlists
+.PP
+YouTube changed their playlist format in March 2014 and later on, so
+you\[aq]ll need at least youtube\-dl 2014.07.25 to download all YouTube
+videos.
+.PP
+If you have installed youtube\-dl with a package manager, pip, setup.py
+or a tarball, please use that to update.
+Note that Ubuntu packages do not seem to get updated anymore.
+Since we are not affiliated with Ubuntu, there is little we can do.
+Feel free to report
+bugs (https://bugs.launchpad.net/ubuntu/+source/youtube-dl/+filebug) to
+the Ubuntu packaging
+guys (mailto:ubuntu-motu@lists.ubuntu.com?subject=outdated%20version%20of%20youtube-dl)
+\- all they have to do is update the package to a somewhat recent
+version.
+See above for a way to update.
+.SS Do I always have to pass in \f[C]\-\-max\-quality\ FORMAT\f[], or
+\f[C]\-citw\f[]?
+.PP
+By default, youtube\-dl intends to have the best options (incidentally,
+if you have a convincing case that these should be different, please
+file an issue where you explain that (https://yt-dl.org/bug)).
+Therefore, it is unnecessary and sometimes harmful to copy long option
+strings from webpages.
+In particular, \f[C]\-\-max\-quality\f[] \f[I]limits\f[] the video
+quality (so if you want the best quality, do NOT pass it in), and the
+only option out of \f[C]\-citw\f[] that is regularly useful is

+.SS On Windows, how should I set up ffmpeg and youtube\-dl? Where should
+I put the exe files?
+.PP
+If you put youtube\-dl and ffmpeg in the same directory that you\[aq]re
+running the command from, it will work, but that\[aq]s rather
+cumbersome.
+.PP
+To make a different directory work \- either for ffmpeg, or for
+youtube\-dl, or for both \- simply create the directory (say,
+\f[C]C:\\bin\f[], or \f[C]C:\\Users\\<User\ name>\\bin\f[]), put all the
+executables directly in there, and then set your PATH environment
+variable (https://www.java.com/en/download/help/path.xml) to include
+that directory.
+.PP
+From then on, after restarting your shell, you will be able to access
+both youtube\-dl and ffmpeg (and youtube\-dl will be able to find
+ffmpeg) by simply typing \f[C]youtube\-dl\f[] or \f[C]ffmpeg\f[], no

+.SS Can you add support for this anime video site, or site which shows
+current movies for free?
+.PP
+As a matter of policy (as well as legality), youtube\-dl does not
+include support for services that specialize in infringing copyright.
+As a rule of thumb, if you cannot easily find a video that the service
+is quite obviously allowed to distribute (i.e.
+that has been uploaded by the creator, the creator\[aq]s distributor, or
+is published under a free license), the service is probably unfit for
+inclusion to youtube\-dl.
+.PP
+A note on the service that they don\[aq]t host the infringing content,
+but just link to those who do, is evidence that the service should
+\f[B]not\f[] be included into youtube\-dl.
+The same goes for any DMCA note when the whole front page of the service
+is filled with videos they are not allowed to distribute.
+A "fair use" note is equally unconvincing if the service shows
+copyright\-protected videos in full without authorization.
+.PP
+Support requests for services that \f[B]do\f[] purchase the rights to
+distribute their content are perfectly fine though.
+If in doubt, you can simply include a source that mentions the
+legitimate purchase of content.
+.SS How can I detect whether a given URL is supported by youtube\-dl?
+.PP
+For one, have a look at the list of supported
+sites (docs/supportedsites.md).
+Note that it can sometimes happen that the site changes its URL scheme
+(say, from http://example.com/v/1234567 to http://example.com/v/1234567
+) and youtube\-dl reports an URL of a service in that list as
+unsupported.
+In that case, simply report a bug.
+.PP
+It is \f[I]not\f[] possible to detect whether a URL is supported or not.
+That\[aq]s because youtube\-dl contains a generic extractor which
+matches \f[B]all\f[] URLs.
+You may be tempted to disable, exclude, or remove the generic extractor,
+but the generic extractor not only allows users to extract videos from
+lots of websites that embed a video from another service, but may also
+be used to extract video from a service that it\[aq]s hosting itself.
+Therefore, we neither recommend nor support disabling, excluding, or
+removing the generic extractor.
+.PP
+If you want to find out whether a given URL is supported, simply call
+youtube\-dl with it.
+If you get no videos back, chances are the URL is either not referring
+to a video or unsupported.
+You can find out which by examining the output (if you run youtube\-dl
+on the console) or catching an \f[C]UnsupportedError\f[] exception if
+you run it from a Python program.

+.SH EMBEDDING YOUTUBE\-DL
+.PP
+youtube\-dl makes the best effort to be a good command\-line program,
+and thus should be callable from any programming language.
+If you encounter any problems parsing its output, feel free to create a
+report (https://github.com/rg3/youtube-dl/issues/new).
+.PP
+From a Python program, you can embed youtube\-dl in a more powerful
+fashion, like this:
+.IP
+.nf
+\f[C]
+import\ youtube_dl
+
+ydl_opts\ =\ {}
+with\ youtube_dl.YoutubeDL(ydl_opts)\ as\ ydl:
+\ \ \ \ ydl.download([\[aq]http://www.youtube.com/watch?v=BaW_jenozKc\[aq]])
+\f[]
+.fi
+.PP
+Most likely, you\[aq]ll want to use various options.
+For a list of what can be done, have a look at
+youtube_dl/YoutubeDL.py (https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py#L69).
+For a start, if you want to intercept youtube\-dl\[aq]s output, set a
+\f[C]logger\f[] object.
+.PP
+Here\[aq]s a more complete example of a program that outputs only errors
+(and a short message after the download is finished), and
+downloads/converts the video to an mp3 file:
+.IP
+.nf
+\f[C]
+import\ youtube_dl

+
