Firstly, navigate to the created list of Resumes. Then click on the icon at the right side of the Resume that you want to update. Select "Edit" from the menu to open a Resume in edit mode.
If you have done changes in your profile e.g added a new project or changed a text or added skills, the system will indicate where the changes have been done.
New projects will be gray and you need to show them by clicking on the eye. For changes within a project the yellow exclamation mark will appear. Open the project by the pen and select to include the changes.
