Downloading from Uploader.jp

I’m very new to flexget.
I read some guides to make a YAML config file but the keys are very specific (i.e: series: or book:) so I can’t understand how to grab archive links from generic RSS and download them.

An example of RSS that I want to subscribe is here.
RSS:https://ux.getuploader.com/com3d2_mod_kyouyu/rss

Please give some hints, references or templates etc…

The simplest config to get everything from an rss feed is:

tasks:
  mytask:
    rss: https://myrssurl.com
    accept_all: yes
    download: /to/here
