You may want to use `python3` instead of `python`

    python -m pip install --upgrade youtube-dlc

To build the Windows executable (a compiled version will be available online soon)

    python -m pip install --upgrade pyinstaller
    pyinstaller.exe youtube_dl\__main__.py --onefile --name youtube-dlc
    
Or simply execute the `make_win.bat` if pyinstaller is installed.
There will be a `youtube-dlc.exe` in `/dist`

# OPTIONS
    -h, --help                       Print this help text and exit
    --version                        Print program version and exit
    -U, --update                     Update this program to latest version. Make
                                     sure that you have sufficient permissions
                                     (run with sudo if needed)
    -i, --ignore-errors              Continue on download errors, for example to
                                     skip unavailable videos in a playlist
    --abort-on-error                 Abort downloading of further videos (in the
                                     playlist or the command line) if an error
                                     occurs
    --dump-user-agent                Display the current browser identification
    --list-extractors                List all supported extractors
    --extractor-descriptions         Output descriptions of all supported
                                     extractors
    --force-generic-extractor        Force extraction to use the generic
                                     extractor
    --default-search PREFIX          Use this prefix for unqualified URLs. For
                                     example "gvsearch2:" downloads two videos
                                     from google videos for youtube-dl "large
                                     apple". Use the value "auto" to let
                                     youtube-dl guess ("auto_warning" to emit a
                                     warning when guessing). "error" just throws
                                     an error. The default value "fixup_error"
                                     repairs broken URLs, but emits an error if
                                     this is not possible instead of searching.
    --ignore-config                  Do not read configuration files. When given

                                     option is not present) is used for the

                                     the "OUTPUT TEMPLATE" for a list of
                                     available keys) to match if the key is

                                     present, key > NUMBER (like "comment_count
                                     > 12", also works with >=, <, <=, !=, =) to
                                     compare against a number, key = 'LITERAL'
                                     (like "uploader = 'Mike Smith'", also works
                                     with !=) to match against a string literal
                                     and & to require multiple matches. Values
                                     which are not known are excluded unless you
                                     put a question mark (?) after the operator.
                                     For example, to only match videos that have
                                     been liked more than 100 times and disliked
                                     less than 50 times (or the dislike
                                     functionality is not available at the given
                                     service), but who also have a description,
                                     use --match-filter "like_count > 100 &
                                     dislike_count <? 50 & description" .
    --no-playlist                    Download only the video, if the URL refers

                                     a video and a playlist.
    --age-limit YEARS                Download only videos suitable for the given
