Saving Custom Data Using the RGSS3 DataManager

So I am wanting to make a quest journal script for ace that requires saving and loading data. I haven't the foggiest clue how to use the datamanager. I don't know how to have it save and load the info I need. I tried to look at ModernAlgerbra's quest script to see if I could decode how he did it, but I can't seem to follow how he saves and loads the data for his quests. I don't need a script to look at, but if I could be pointed to a topic that explains how it works or if I could get a link to a tutorial that would be awesome. Until then, I'll be trying to find tutorials on my own.

pretty much everything is saved into the contents object.
find the function make_save_contents within DataManager.
it's just that: contents[:symbol] = data.

Okay, now how do you do the same for loading the contents back out? When I went and made my class Game_Quests, I added a $game_quests = Game_Quests.new() and then made the symbol for it. But, when I followed the load save content one it kept erroring out. I'll take another look at it in the morning. But thank you for confirming I was on the right track.

................ maybe read the function "extract_save_contents" which is right below "make_save_contents" ?
