In addition to the raw data you can upload into Pluto, and the interactive analysis you can perform, there may be additional files that you want to store. This could include:
Protocols
Manuscripts and other documents
Images
Publication-ready figures
Any other documents or images that are relevant to the experiment
Experiment Attachments are a great way to store these files in one place, so that anyone with access to the experiment can find all of the relevant information.

To upload attachments, click on the Attachments tab on the experiment and either drag and drop your files into the area inside the dashed line, or click the button to select files from your computer.
