+You can use the **Tracking** panel to see the list of parameters that the **puppet** was rigged with. By default, for each parameter you will see a widget that will let you select either a specific parameter from the currently connected **tracking sources**. You can either pick a specific **parameter** of one of the **bones** or the name of a **blendshape** to asociate the **parameter** to it.
+\\
+\\
+Be aware that the software won't try to detect which **bones** or **blendshapes** are available from connected **tracking sources** until you press the "**Refresh**" button in the **Tracking** panel. Also, there are many things that can get configured for a specific **parameter**.

+When rigged, **puppet** **parameters** are usually set up so that they deform the puppet by a specific amount, usually between -1 and 1, or 0 and 1, but this doesn't always align with the input **bone** or **blendshape** data values. **Bone** position values and **blendshapes** usually can come in values between -inf and inf, but some of them only move between 0 and 1, while **bone** rotation values usually come in angle degrees (-180 and 180).
+\\
+\\
+To make the **tracking** data match with **parameter** values, the **Tracking In** and **Tracking Out** intervals are used. For the context of a specific parameter, the **tracking data** will be clamped to the **Tracking In** range, and it will be transformed to the values of the **Tracking Out** range, which are the ones used by the **puppet parameter**. You can see how these behave by looking at the yellow bars. You can also press the **Inverse** checkbox to flip the input data.
