If you have a document to support a task, this can be uploaded to MindGenius Online and will be displayed in the Task Card.
To upload a file, click on the branch you want to attach to then open when in Map view, select Links -> Add Link/Attachments -> Local File. A drop-down of options will appear giving you several options of where to retrieve the attachment from, you should locate and attach the file you want.
Alternatively, you can select the file on your device and drag it onto the browser window. The Task Card will change to display a box which you can drop the file to attach it to the task.
