+## Capabilities Information
+
+### Bottom Up
+
+These shades offer only the simple up/down movement of your conventional shades.
+
+### Top Down
+
+<div class="note">Full functionality not currently implemented</div>
+
+These shades offer a unique movement that is inverse to your conventional shade, where the shade is fixed to the floor and lowered from the roof.
+
+### Top Down, Bottom Up (TDBU)
+
+<div class="note">Full functionality not currently implemented</div>
+
+TDBU shades consist of two rails controlled by two motors designated by Top and Bottom with fabric in between.
+The Top and Bottom can move independently to cover different parts of the window but cannot pass the other.
+Two different entities that will be created for each blind: Top and Bottom.
+
+#### Top entity
+
+- 'Up/Open' will move the Top rail to the bottom of the window and set the Bottom rail to its closed position.
+- 'Down/Close' will move the Top rail to the top of the window and set the Bottom rail to its closed position.
+- 'Position' is the position in which the Top rail can move from the top of the window (0) to the bottom (100).
+- The position of a Top rail cannot pass that of a Bottom rail. If you set an impossible position, the position will fall back to the closest possible value to that requested.
+
+#### Bottom entity
+
+- 'Up/Open' will move the Bottom rail to the top of the window and set the Top rail to its closed position.
+- 'Down/Close' will move the Bottom rail to the bottom of the window and set the Top rail to its closed position.
+- 'Position' is the position in which the Bottom rail can move from the bottom of the window (0) to the top (100).
+- The position of a Bottom rail cannot pass that of a Top rail. If you set an impossible position, the position will fall back to the closest possible value to that requested.
+
+### Tilt when closed
+
+Shades with Tilt when closed functionality only allow a shade to tilt when it is closed and will automatically close the vanes when the shade is moved from it's closed position.
+
+### Tilt Anywhere
+
+<div class="note">Full functionality not currently implemented</div>
+
+These shades can tilt in any position and do not require the shade to be open or closed to adjust the tilt position.
+
+### Dual Shade Blackout
+
+<div class="note">Full functionality not currently implemented</div>
+
+These shades consist of two pieces of fabric attached to a single rail. The front shade is sheer, with the rear being blackout, and neither panel can move independently from the other.
