 Partially inspired by [hobune](https://github.com/rebane2001/hobune). While that project is amazingby it's own, it's just not scaleable.
 
 ## The idea
-Having over 250k videos, scaling the current cronjob yt-dlp archive task is just really hard. Filetypes change, things get partially downloaded and such.
+Having over 350k videos, scaling the current cronjob yt-dlp archive task is just really hard. Filetypes change, things get partially downloaded and such.
 Partially yt-dlp is to blame because it's a package that needs to change all the time. But with this some changes are not accounted for.
 yt-dlp will still do the downloads. But a flask frontend will be developed to make all downloaded videos easily indexable.
 For it to be quick (unlike hobune) a database has to be implemented. This could get solved by a static site generator type of software, but that is not my choice.
