The most important starting task was building a good working relationship with the book’s author. I wanted him to be comfortable with my technical editing style and okay with getting criticism. After all, he had written a great book, but my job was to make it even better.
Once the editing was in full swing, I focused on getting the sample code in the book to work as described. There were frequently compiler errors in Visual Studio code, and I had to debug them or report the errors to the author. Once the code samples were finalized, I maintained them in a repository so they could be distributed along with the written contents.
Finally, I also fact checked the book’s factual claims to make sure there were no inadvertent inaccuracies.
