+# Configuring the Body Model
+
+The body model can be configured in multiple ways. This include what limb
+segments are include, the type of muscles, scaling etc.
+
+All these choises are controlled through a number of switches called Body Model
+(BM) parameters. BM parameters are always prefixed with `BM_` and written in
+uppercase.
+
+## Simple example
+
+The example below configures a model with no arms and enables the 3-element Hill
+muscles model on the legs.
+
+:::{note}
+:class: margin
+Some parameters have simple {ammr:bm_constant}`ON`/{ammr:bm_constant}`OFF`
+options, while others have more options. 
+:::
+
+```{code-block} AnyScriptDoc
+:emphasize-lines: 1-3
+
+#define BM_ARM_LEFT OFF
+#define BM_ARM_RIGHT OFF
+#define BM_LEG_MUSCLES_BOTH _MUSCLES_3E_HILL_
+
+// Now include the HumanModel
+#include "<ANYBODY_PATH_BODY>\HumanModel.any"
+```
+
+
+
+The next section shows an overview of what BM statements are available for the different body parts.
+
+## BM parameters
+
+:::{tip}
+:class: margin
+Most models can also be configured using the
+{doc}`BM plugin </bm_config/bm_plugin>`.
+:::
+
+There are body model parameters for configuring each body part, controlling scaling, controlling the default
+mannequin drivers (click to see tutorial on {ref}`modelling from scratch <MannequinDriver>`), as well as other global options for the model.
+
+See the following links for details on BM parameters related to different body parts and modelling options:
