+or
+* User cannot see documents from cloud services
+-->
+
+# Goals & use cases
+<!--
+What are the use cases that this proposal will cover? What are the end goals?
+
+For example:
+* User needs to share a file with their friends.
+or
+* It should be easy to edit a picture within the app.
+-->
+
+# Requirements
+<!--
+What does the solution needs to ensure for being succesful?

+# Relevant art
+<!--
+Is there any product that has implemented something similar? Put links to other
+projects, pictures, links to other code, etc.
+-->
+
+# Proposal & plan
+<!-- What's the solution and how should be achieved? It can be split in smaller
+tasks of minimum change, so they can be delivered across several releases. -->
