About Fedora Media Writer, the description of the website of webpage
https://getfedora.org/en/workstation/prerelease/
is incorrect.

Though there is the sentence "4. Select "Custom OS..." from the list." on the webpage, but in actual app, the "Custom OS..." button isn't exist.
Instead, "Custom image" is exist.

And though there is the sentence "5. On the Custom OS page, select the "Select Live ISO" button." , but "Select Live ISO" button is not exist too in the actual app.
