+###Clone the overlay
+Create a local checkout of the overlay
+ hub clone gentoo-science/sci
+
+###Fork the overlay
In order to send pull request and ask for inclusion of your changes you need to have your own fork of the overlay on github. You can do this by issuing
cd sci
hub fork
-Now you are ready to start your work.

+###Branch out for contribution
It is always convenient for development as well as for the review and merging process, if the development is done in branches.
git checkout -b my-feature master

+ repo-commit "Here we write a comprehensible commit message"
+###Push to Github and make a pull request
Next we push back the changes to our fork and send a pull-request to the overlay maintainers.
hub push YOUR_GITHUB_USER
hub pull-request
-Lastly you need to wait for review comments and the merge of your work. In case you need to include some improvements, just commit your work again using repoman and push it again to your fork. No need to send another pull-request as your new changes will be added to the original one.
