Getting your media player to see SiaStream
You need to tell your media player to look at SiaStream so it can see your media. Specifically, you point it to the FUSE mount that you set up during the onboarding.
A quick example
Open your media player. We'll use Plex for right now. Go to Movies and click on the Ellipsis (...) to access your settings. Click on Manage Library and then Edit.

Click Add Folder in the left sidebar, and then add the folder that you set for your FUSE mount.

Plex will now see your media library in SiaStream. Don't worry if you are already pointing to your local media library - Plex is smart enough to not duplicate the files.
