     h1 Google Drive Userscript
-    h2 Why?
-    p.
-      Since Google Drive support was launched in early 2014, it has broken
-      at least 4-5 times, requiring increasing effort to get it working again
-      and disrupting many channels.  This is because there is no official API
-      for it like there is for YouTube videos, which means support for it
-      relies on undocumented tricks.  In August 2016, the decision was made
-      to phase out the native support for Google Drive and instead require
-      users to install a userscript, which allows to bypass certain browser
-      restrictions and make the code easier, simpler, and less prone to failure
-      (it could still break due to future Google Drive changes, but is less
-      likely to be difficult to fix).
