Upload guide lines

We should make a text describing upload guide lines to explain which files are allowed. We suggest that only very specific files can be uploaded such as json and txt files (and other optional files as suggested in the list below). Also images should only be uploadable if the correct size.

For all
Required
Cover image 200x200

Protein design
Required
Optional

No target file, test, or entry point is named. Start by reviewing the requested categories and confirming the allowed formats and image dimensions, especially the incomplete Protein design section and the unclear optional-file entries. Done means a text guide clearly documents the required and optional uploads for each design type.
