+## General
+## probMethods
+Probmethods are used to join the multiple similarity results from multiple models, and multiple datapoints into one single value.
+
+The probMethod is given a list where each element consists of a string and a floating point value (0-1).
+
+### `probmethod_embedding` (also referred to as `probmethod_datapoint`)
+Takes list where each element contains:
+- model name (e.g. "bge-m3")
+- Result of the similarity calculation between query embeddings and the embeddings for this datapoint (per model)
+
+Returns a single floating point value that represents the resulting similarity for this datapoint.
+### `probmethod` (also referred to as `probmethod_entity`)
+Takes list where each element contains:
+- datapoint name (e.g. "title", "text", "filename")
+- Result from `probmethod_embedding`
+
+Returns a single floating point value that represents the resulting similarity for this Entity.
 ## Python
 To ease scripting, tools.py contains all definitions of the .NET objects passed to the script. This includes attributes and methods.

 ### Using the toolset passed by the .NET CLR
 The use of the toolset is laid out in good example by `src/Indexer/Scripts/example.py`.
