Hello, I am writing a book about programming. I would like to know if there are free&#x2F;open templates I can use for this. I was also thinking about the tools. I use to write in tex&#x2F;latex, is there anything else I must consider? I don&#x27;t like Office or similar. 
BTW, I have written many pages (a lot) and I am looking for some way to get a &quot;preview&quot; of the final product. As you can see, this is a one-man operation. Thank you!
