What do I need to do?

Hi, I want to use the script but I don't know where I can put which video's and channels I want to be hidden.

You need to edit this part of the code:
var videoMatchHide = {};
videoMatchHide['Arumba'] = ['Punch Club', 'Arumba Plays The Binding of Isaac', 'EUIV', 'Hero Defense Haunted Island'];
videoMatchHide['EnterElysium'] = ['XCOM 2'];
videoMatchHide['*'] = ['Crashlands', 'Lego Marvel Avengers', 'Train Valley'];
For example this code will hide videos 'Punch Club', 'Arumba Plays The Binding of Isaac', 'EUIV', 'Hero Defense Haunted Island' from channel 'Arumba', 'XCOM 2' videos from channel 'EnterElysium' and 'Crashlands', 'Lego Marvel Avengers', 'Train Valley' from all channels.
