Authors, companies and universities use Leanpub to easily write, publish and sell amazing in-progress and completed ebooks and online courses.

By the way, this is a sign up page, but you actually don't need to sign up here!

We automatically create an account for you if you buy something. This is because many of our books and courses are published in-progress, and you get free updates whenever an author publishes a new version. So, please feel free to browse the Leanpub homepage or search the Leanpub store.

We also automatically create an account for you if you create a book or course. Leanpub authors can create up to 100 books or courses for free, or choose a Standard or Pro plan for more features.

So why does this page exist? Simple: when it didn't, people asked us where it was. So, it's here, and you can use it if you wish!
