In order to contribute to GNOME developing applications it is not required start from stratch which sometimes could be intimidating for newcomers. Also, looking specific parts of a big piece of code could intimidating to start with. While it is possible start using tools such as cscope, not everyone feels comfortable when is a beginner in a long live open source project.

The objective of this tutorial is to help to new potential GNOME's developers to get custom with the applications in GNOME Desktop that are user every day and show how easy and fun could be add them features or extend them getting results quickly.

For this tutorial I have choosen Nautilus and gEdit as applications to be extended. Nautilus, because the impact it has from day to day and because it is easy to mix them with small script shells, that normally everyone writes. And gEdit, because it allows to work with documents and it is possible to getting familiar with more complex widgets.
