Documentation Improvement: Clarify Editing Requirements

[lagerdigal1996]

Issue Description

The README provides an overview of the tools used for creating and editing the prototypes, specifically mentioning Inkscape and GIMP. However, it could be improved by adding specific versions or additional details about plugins/extensions that may be required for optimal use of these tools.

Suggested Changes

1. Include the specific versions of Inkscape and GIMP that are necessary for compatibility with the artwork files provided in the repository.
2. Mention any recommended plugins or extensions for both Inkscape and GIMP that enhance functionality and user experience.
3. Add a short tutorial or checklist to help new users set up their environments for editing the prototypes effectively.

This would significantly help users who are unfamiliar with these tools and reduce potential barriers to contributing or utilizing the prototypes effectively.
