How does it work?

[MaxiDorado]

(This is the first thing I've done on Github since I created my account, sorry if I did something wrong, I don't know how to use Guthub)

I learned the basics of CellPond by watching YouTube videos and experimenting a little, but there are some very complex things like what are the up and down triangles for? (I only know how to use the one that points to the right), or what is the - for? There are many things I would like to learn but the only thing I find is "It's a secret.", it may be complicated to write a manual or something, but it would be very useful
