Image Processing tutorials for Siril?

Wow, I have just come across Siril and tried my first attempt at using the DSLR Scrip and it is magic. The easy and accuracy of doing this compared to Nebulosity with the same set of images is astounding. I’m left at the end of the YouTube tutorial on the subject and have no idea how to process the resulting image. I have the result file. I opened it in Siril and have a really super Blue channel, okay red and green and a weird RGB image that is washed out with a green overlay. Can anyone point me to a tutorial on image processing in Siril?
