You can edit a project by going to the project overview and click on the three little dots on the right. You can decide between editing or deleting the project. When you click on edit, there is a new pop-up where you can edit the project details.
When editing a project, you can change the following fields:
- Project Name
- Start Date
- Due Date
- Planned Effort
Afterwards just click save and you are done.
Editing a project is only possible if you have "Manage" permissions for "project manage".
