Thanks! I don't know if I could fix all the grammar, but the spelling nazi in me wants to correct those mistakes for sure.
Maybe the PDF is designed for smaller screens . It looks better on an iPad or android tablet. I used the .mobi instead to wipe out the font anguish. ;-)
Pretty ugly font for a manual.
Translation is a little iffy, bad spelling, bad grammar and strange sentence structure.
Graphics and diagrams are quite lossy and low resolution.
It could definitely do with another proofread or three.
But If you can get past these things it seems pretty thorough and has plenty of good info in there. Hopefully none of it was lost in translation.
I also donated and am happy to finally see it out there especially under creative commons.
