You have a
+ button on the main reading page and on categories pages:
Clicking on this button opens a window for adding a link:
Enter a valid link. You can also specify a category. If the page is readable it will be added to the reading flow.
A page can only be added once.
Attention: The page may not be readable by the content extraction system. This is usually due to a deliberate obfuscation to prevent this kind of extraction. In this case, only Open Graph data are extracted.
