Using a "hosts" file to ad-block

Sorry I did not get it.
What to to with the link? Copy it and save it as…?
Which archive where to get it?
If I open the link there is nothing to download or clone?

Sorry this is not easy to follow for me

Edit:
I installed hblock from HaikuDepot. In terminal I started “hblock”… It generated the block-list file “hosts” as mime-text file in boot/system/settings/network/

This means I can just copy and paste the StevenBlack’s list into a text-file and overwrite the automatic generated file by hblock “hosts” in boot/system/settings/network/
