Everybody who uses Sage should contribute something back to Sage at some point. Implement a new function, add examples to the documentation, find bugs and typos, fix a bug, create a new class, create a fast new C library, etc. This book is a guide about how to contribute to Sage.
This document describes how to write programs using Sage, how to modify and extend the core Sage libraries, and how to modify Sage's documentation. It also discusses how to share your new and modified code with other Sage users.
