Hi Ian
You should get the document source from Gus and edit it.
pg 20
“…module, in software or physically…” ?
“…on the LED module until the pointer changes.”
Is this supposed to say “Now, click on the XY socket of the LED module.”?
“module”
“Let’s now click on socket 4 on the mainboard.”
pg 22
“starts”
“…threads, and dynamic allocation.”
“…will come later.”
“…turns the LED off, waits again, then loops back”
“…and type “led” then hit the “dot” (period) key”
“…with Intellisense, Visual Studio…”
pg 23
" has a Red…"
no comma needed
“…hit the F5 key”
“…in a few seconds…”
“…key an eye…”
pg 27

“These files already include the correct Gadgeteer socket, hole sizes, silkscreen, logos and [???] sizes.”
@ rajesh If I’d known where this was going to end up, it definitely would have been easier to start out that way 
@ Gus I’m going to resume on page 29 tomorrow. If you want to email me something in .doc format, I’ll be glad to edit in place or keep doing it this way.
I was going to say, yes I would love for you and other to contribute. There is a reason why the book is open source
I was planning on finishing couple more things and then post the source up.
pg 29
“makes”
“…is very simple.”
“…has lower risk.”

pg 32
“You also need JTAG to step into code for debugging.”
“Additionally, how would the end sample prototype or proof of concept look when presented to the investor?”

Done. Great job, Gus!
