You often learn more from others (or your own) mistakes than by reading how to do it right. It can also be more constructive.
As to "I don't know how", that is not a valid answer. If someone said to you "How did you set up this great tank you have here?" you wouldn't say "I don't know", you would tell them a basic step by step. When writing, imagine someone has asked you "How did you do (breed, build, make etc) that?" and go from there.
As said, I can correct grammar and spelling as required.
Please, give it a go.
