How to make a save and load option

I have done some searching on this already but I still dont know how to make a save and load option. What I am trying to do is make it so I can save where I am at in the story line which will be built up of different scenes and when I save it records what scene I left of on so the next time I can click on a load game option in the main menu and start from that scene and repeat those steps, it will save into the game itself. If someone could point me in the right direction on how to do this that would be great I am new to scripting with javascript and C# and never tried boo so please try to keep things as simple as possible, thank you.

If there is any additional info needed ask and I will post it a comment if I can.

I answered a similar question some time ago:

And another one showing how to save some more complex info, like rotation and position:

There’s a script on the UnifyCommunity Wiki for loading and saving, which should meet your needs with a little adjustment.
