Getting started with gitbook
Create a new repo at github. It will need at least 2 files: Summary.md and readme.md. (The rest of the content of your book will be markdown files, and images, in that same repo)
Readme.md is treated as the cover-page/introduction to the book
Summary.md is used to build the table of contents. It starts with the line "# Summary" and has a link to everything you want to include.
So it looks like this (for example)
# Summary
- asp.net mvc
- [clear caches](../asp.net_mvc/clear_caches.html)
- [elmah](../asp.net_mvc/elmah.html)
- [from memory](../asp.net_mvc/from_memory.html)
- [helpful error page](../asp.net_mvc/helpful_error_page.html)
- [return 404](../asp.net_mvc/return_404.html)
- [serve some static files from mvc but not all](../asp.net_mvc/serve_some_static_files_from_mvc_but_not_all.html)
- git
- [how to git](../git/how_to_git.html)
I generate that file using pre though it's easy enough to generate with a bit of powershell.
In gitbook you sign up, and create a "New Book".
Tell it the location of your github repo and also set up a webhook so that when the repo is updated gitbook is notified. I documented that bit already: To have your gitbook updated whenever you push to a github repo
Thereafter, any time you push to your github repo it will be immediately updated on gitbook!
You can also generate a gitbook and preview it locally -- see use gitbook locally
(Not recommended: writing/editing the content directly at gitbook.com: that won't work out over time. Better to use a full repo from the start)
