+#### Making OBS scenes
+
+Making OBS scenes is pretty straightforward as you can move the
+different blocks on your scene in the preview window. However, it’s
+important to make sure that your video-captures and your overlays are
+snapping properly to the edges of the view-port. To do this, make sure
+to right-click on the block inside the preview window, and try the
+different fitting options (fit by width, height, etc.) until you find
+one that works best.
+
+We’ll probably be streaming at 720p, but since we’re also considering
+a 1080p update, try to create your overlays in a format or a resolution
+that would support resizing.
+

### Other notes
There are sockets in the home directory for MPV control if you want to keep that process.
