+*The "Content about" section **should not** be more than **1** line. In this section, describe the main content of the channel.*
+*The "Featured playlists" section **should not** be more than **2** lines. In this section, put the best playlists of the youtuber. This is because as the youtuber should at least teach (maybe not explicitly) something according to its channel content. It doesn't have to be a literal YouTube playlist though; this is preferable, but if the youtuber doesn't have any playlist, you can consider as a playlist a series of videos. If still you consider the youtuber doesn't have any playlists, you can type "`None`".*
