Howto patch a Drupal module

Some contributtion to add to this Drupal module with which you have been working on?

Very easy, take note:

1. Go to the folder of your module, previously cloned with git. For example, my contribution this morning: 
2. git clone --recursive --branch 7.x-1.x http://git.drupal.org/project/cpn.git
3. cd cpn
4. Create a new branch, for example: git branch 1912834-weight
5. Change to this branch to make the changes: git checkout 1912834-weight
6. Make your changes
7. Add them with: git add your-file-modified
8. Commit them, git commit -m "comment your changes as much as possible"
9. Create your new patch: git diff 7.x-1.x > cpn-weightsettings-1912834.patch
10. That's it :-)
