How to modify files in your branch on github

You created and released a new branch following the RERO development philosophy paradigm. Later on you discover that there are some bugs that you would like to fix in your branch and publish.

Problem

How to fix a file in a branch.

Solution

We need to checkout the branch from repository.
Modify the file and fix the issue.
Commit the changes back to our branch.

An example session is showed below.

 
git checkout challenge2
#now you modify the file, once done
git commit -m 'fixed delete_images func' -a
git push origin

# after modification we want to return in default branch
git checkout master
git branch
