To edit a project you created or for which you are an administrator, return to the pages you used for the creation of your project.
On the Home page, go to the Recent Projects section. Select the project you want to edit in the scrolling menu on the right.
When you select your project, it will appear below. You can then see all details. To edit click on the pen button.
You will land on the page used to create your project with the four same categories: Project details, Geographic Areas, Users, Analytical Framework. You can roam the categories, delete the unwanted fields and add or change what is needed. Either delete and type new text, click on the bin icon, click on the add buttons or click on the pen buttons depending on the fields. For more information, please refer to the Set up a new project section.
