+.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+Note that distribution packages are often outdated.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+distributions serves a really outdated version.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[]

+Afterwards, simply follow our manual installation

+.SS I\[aq]m getting an error
+\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+guys (mailto:ubuntu-motu@lists.ubuntu.com?subject=outdated%20version%20of%20youtube-dl)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
+\f[C]\-i\f[].

+\f[C]C:\\bin\f[], or \f[C]C:\\Users\\<User\ name>\\bin\f[]), put all the

+.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
+
+
+class\ MyLogger(object):
+\ \ \ \ def\ debug(self,\ msg):
+\ \ \ \ \ \ \ \ pass
+
+\ \ \ \ def\ warning(self,\ msg):
+\ \ \ \ \ \ \ \ pass
+
+\ \ \ \ def\ error(self,\ msg):
+\ \ \ \ \ \ \ \ print(msg)
+
+
+def\ my_hook(d):
+\ \ \ \ if\ d[\[aq]status\[aq]]\ ==\ \[aq]finished\[aq]:
+\ \ \ \ \ \ \ \ print(\[aq]Done\ downloading,\ now\ converting\ ...\[aq])
+
+
+ydl_opts\ =\ {
+\ \ \ \ \[aq]format\[aq]:\ \[aq]bestaudio/best\[aq],
+\ \ \ \ \[aq]postprocessors\[aq]:\ [{
+\ \ \ \ \ \ \ \ \[aq]key\[aq]:\ \[aq]FFmpegExtractAudio\[aq],
+\ \ \ \ \ \ \ \ \[aq]preferredcodec\[aq]:\ \[aq]mp3\[aq],
+\ \ \ \ \ \ \ \ \[aq]preferredquality\[aq]:\ \[aq]192\[aq],
+\ \ \ \ }],
+\ \ \ \ \[aq]logger\[aq]:\ MyLogger(),
+\ \ \ \ \[aq]progress_hooks\[aq]:\ [my_hook],

+.SH BUGS
+.PP
+Bugs and suggestions should be reported at:
+<https://github.com/rg3/youtube-dl/issues> .
+Unless you were prompted so or there is another pertinent reason (e.g.
+GitHub fails to accept the bug report), please do not send bug reports
+via personal email.

 For discussions, join us in the irc channel #youtube\-dl on freenode.
 For discussions, join us in the irc channel #youtube\-dl on freenode.

+.PP
+\f[B]Please include the full output of youtube\-dl when run with
+\f[C]\-v\f[]\f[].
+.PP
+The output (including the first lines) contain important debugging
+information.
+Issues without the full output are often not reproducible and therefore
+do not get solved in short order, if ever.
+.PP
+Please re\-read your issue once again to avoid a couple of common
+mistakes (you can and should use this as a checklist):
+.SS Is the description of the issue itself sufficient?
+.PP
+We often get issue reports that we cannot really decipher.
+While in most cases we eventually get the required information after
+asking back multiple times, this poses an unnecessary drain on our
+resources.
+Many contributors, including myself, are also not native speakers, so we
+may misread some parts.
+.PP
+So please elaborate on what feature you are requesting, or what bug you
+want to be fixed.
+Make sure that it\[aq]s obvious
+.IP \[bu] 2
+What the problem is
+.IP \[bu] 2
+How it could be fixed
+.IP \[bu] 2
+How your proposed solution would look like
+.PP
+If your report is shorter than two lines, it is almost certainly missing
+some of these, which makes it hard for us to respond to it.
+We\[aq]re often too polite to close the issue outright, but the missing
+info makes misinterpretation likely.
+As a commiter myself, I often get frustrated by these issues, since the
+only possible way for me to move forward on them is to ask for
+clarification over and over.
+.PP
+For bug reports, this means that your report should contain the
+\f[I]complete\f[] output of youtube\-dl when called with the \-v flag.
+The error message you get for (most) bugs even says so, but you would
+not believe how many of our bug reports do not contain this information.
+.PP
+Site support requests \f[B]must contain an example URL\f[].
+An example URL is a URL you might want to download, like
+http://www.youtube.com/watch?v=BaW_jenozKc .
+There should be an obvious video present.
+Except under very special circumstances, the main page of a video
+service (e.g.
+http://www.youtube.com/ ) is \f[I]not\f[] an example URL.
+.SS Are you using the latest version?
+.PP
+Before reporting any issue, type youtube\-dl \-U.
+This should report that you\[aq]re up\-to\-date.
+About 20% of the reports we receive are already fixed, but people are
+using outdated versions.
+This goes for feature requests as well.
+.SS Is the issue already documented?
+.PP
+Make sure that someone has not already opened the issue you\[aq]re
+trying to open.
+Search at the top of the window or at
+https://github.com/rg3/youtube\-dl/search?type=Issues .
+If there is an issue, feel free to write something along the lines of
+"This affects me as well, with version 2015.01.01.
+Here is some more information on the issue: ...".
+While some issues may be old, a new post into them often spurs rapid
+activity.
+.SS Why are existing options not enough?
+.PP
+Before requesting a new feature, please have a quick peek at the list of
+supported
+options (https://github.com/rg3/youtube-dl/blob/master/README.md#synopsis).
+Many feature requests are for features that actually exist already!
+Please, absolutely do show off your work in the issue report and detail
+how the existing similar options do \f[I]not\f[] solve your problem.
+.SS Is there enough context in your bug report?
+.PP
+People want to solve problems, and often think they do us a favor by
+breaking down their larger problems (e.g.
+wanting to skip already downloaded files) to a specific request (e.g.
+requesting us to look whether the file exists before downloading the
+info page).
+However, what often happens is that they break down the problem into two
+steps: One simple, and one impossible (or extremely complicated one).
+.PP
+We are then presented with a very complicated request when the original
+problem could be solved far easier, e.g.
+by recording the downloaded video IDs in a separate file.
+To avoid this, you must include the greater context where it is
+non\-obvious.
+In particular, every feature request that does not consist of adding
+support for a new site should contain a use case scenario that explains
+in what situation the missing feature would be useful.
+.SS Does the issue involve one problem, and one problem only?
+.PP
+Some of our users seem to think there is a limit of issues they can or
+should open.
+There is no limit of issues they can or should open.
+While it may seem appealing to be able to dump all your issues into one
+ticket, that means that someone who solves one of your issues cannot
+mark the issue as closed.
+Typically, reporting a bunch of issues leads to the ticket lingering
+since nobody wants to attack that behemoth, until someone mercifully
+splits the issue into multiple ones.
+.PP
+In particular, every site support request issue should only pertain to
+services at one site (generally under a common domain, but always using
+the same backend technology).
+Do not request support for vimeo user videos, Whitehouse podcasts, and
+Google Plus pages in the same issue.
+Also, make sure that you don\[aq]t post bug reports alongside feature
+requests.
+As a rule of thumb, a feature request does not include outputs of
+youtube\-dl that are not immediately related to the feature at hand.
+Do not post reports of a network error alongside the request for a new
+video service.
+.SS Is anyone going to need the feature?
+.PP
+Only post features that you (or an incapacitated friend you can
+personally talk to) require.
+Do not post features because they seem like a good idea.
+If they are really useful, they will be requested by someone who
+requires them.
+.SS Is your question about youtube\-dl?
+.PP
+It may sound strange, but some bug reports we receive are completely
+unrelated to youtube\-dl and relate to a different or even the
+reporter\[aq]s own application.
+Please make sure that you are actually using youtube\-dl.
+If you are using a UI for youtube\-dl, report the bug to the maintainer
+of the actual application providing the UI.
+On the other hand, if your UI for youtube\-dl fails in some way you
+believe is related to youtube\-dl, by all means, go ahead and report the
+bug.
