@tiberiuichim Here you go:
Problem Statement: A new developer working on Volto would incorrectly assume that all the Semantic UI font Icons would be available for use in Volto.
Use Case: The developer would like to use Semantic-UI 'legal' font icon as common disclaimer content icon.
Suggested Solution: Clearly state that Volto uses only a subset of Semantic UI icons in FAQs and also in Plone training docs.
Suggested Enhancement: Provide simple instructions to override and import additional Semantic UI icon fonts as needed using volto customization files (icon.overrides et al).
