So far, all the feedback has been positive.
Already, I have thought of things left out, so these will be included in an issue 2 later.
Feel free to download the free book if you want. You can keep it as a soft copy or print out relevant pages.

UPDATE 1306z: Someone in the USA has very kindly made a donation. Thank you! As I have said before, I have absolutely no wish to make any money at all from this book. It is a labour of love. I shall give this to the local foodbank, but I really appreciate the kindness.
