+# Getting Started
+
+The *AnyBody Managed Model Repository* (AMMR) is a comprehensive open library of
+musculoskeletal models and examples designed to use with the AnyBody Modeling
+System. It allows users to configure and combine different body models, which
+can be easily integrated into their own simulations and analyses.
+
+The AnyBody Managed Model Repository (AMMR) is included with the 
+[AnyBody Modeling System](https://www.anybodytech.com), 
+but it needs to be manually installed or unpacked after installing AnyBody. You
+can install the AMMR from the *AnyBody Assistant* dialog that appears when
+AnyBody starts. For more information on how to install the AMMR, see the next
+lesson {ref}`Installing Latest AMMR Files <installing-ammr>`.

+% 1.. rubric:: Before using AMMR
+
+## Opening an AMMR Model
+
+To begin editing AMMR models, first navigate to the 'AMMR' folder in your file
+explorer and open the 'Application' folder. Here, you will find all the
+available models and examples. Navigate to the model you want to work on and
+copy its containing folder and paste it into your working directory. The first
+line in the main file of the model includes the 'libdef.any' file from the AMMR
+folder. To correctly reference this file, add the following line at the beginning 
+of the main file.
+
+```AnyScriptDoc
+#include "<ANYBODY_PATH_INSTALLDIR>/AMMR/libdef.any"
+```
+
+## Understanding the AnyScript Models
+
+Most examples you will encounter when using the AnyBody Managed Model Repository
+use the {ref}`Human Model <the-body-model>`. Regardless of complexity, all
+models share a common structure used to set them up.
+
+The models will typically look like this:
+
+```AnyScriptDoc
+#include "path_to_AMMR/libdef.any"
+
+Main =
+{
+  // Configure and include the Human Model
+  #define BM_LEG_MODEL _LEG_MODEL_TLEM2_
+  #define BM_ARM_LEFT OFF
+  #define BM_ARM_RIGHT OFF
+  #include "<ANYBODY_PATH_BODY>/HumanModel.any"
+
+  // Compose the model
+  AnyFolder Model =
+  {
+    AnyFolder &BodyModel = .HumanModel.BodyModel;
+    AnyFolder Drivers = {...};
+    AnyFolder Environment = {...};
+  };
+
+  // Configuring the Study
+  AnyBodyStudy Study =
+  {
+    AnyFolder &Model= Main.Model;
+    Gravity = {0,-9.81,0}; // Gravity Vector
+    nStep = 10; // Number of steps
+    tStart = 0; // Start time
+    tEnd = 10.0; // End time
+  };
+};
+```
+
+Let us go through the different components to understand how they work.
+
+### Path to AMMR
+
+```AnyScriptDoc
+#include "path/to/AMMR/libdef.any"
+```
+
+When having multiple versions of AMMR available on your computer, you have to
+specify which one will be used by AnyBody. Each AMMR includes a file called
+`libdef.any` located at the top-level folder. The AnyScript line, used for
+instructing AnyBody which AMMR to use, should be at the very beginning of your
+`.any` file.
+
+### Configuring the Human Model
+
+:::{seealso}
+:class: margin
+{doc}`The documentation on BM configuration </bm_config/index>`
+:::
+
+```AnyScriptDoc
+Main =
+{
+  // Configure and include the Human Model
+  #define BM_LEG_MODEL _LEG_MODEL_TLEM2_
+  #define BM_ARM_LEFT OFF
+  #define BM_ARM_RIGHT OFF
+```
+
+The Human Body Model is configured through a number of `#define` and `#path`
+statements. These statements are all prefixed with `BM_` inside AnyScript, and
+they can also be referred to as "bm-statements". They define which parts of the
+human body model are included or excluded.
+
+### Including the Human Model
+
+```AnyScriptDoc
+#include "<ANYBODY_PATH_BODY>/HumanModel.any"
+```
+
+After the configuration statements, the HumanModel is included. It is important
+that the configuration statements are placed before this line.
+
+### Composing the Model
+
+```AnyScriptDoc
+AnyFolder Model =
+{
+  AnyFolder &BodyModel = .HumanModel.BodyModel;
+  AnyFolder Drivers = {...};
+  AnyFolder Environment = {...};
+};
+```
+
+Most examples have a section where the model is composed. This is where we
+combine the `Body` from the HumanModel, and add extra things like drivers,
+external loads, and constraints.
+
+It could also be any models of the environment which the body interacts with.
+
+### The Study section
+
+```AnyScriptDoc
+AnyBodyStudy Study =
+{
+  AnyFolder &Model= Main.Model;
+  Gravity = {0,-9.81,0}; // Gravity Vector
+  nStep = 10; // Number of steps
+  tStart = 0; // Start time
+  tEnd = 10.0; // End time
+};
+```
+
+:::{seealso}

+{doc}`The full tutorial on how to create a HumanModel from scratch </creating_model_from_scratch>`
+:::
+
+The `AnyBodyStudy` is where you configure and define your simulation. It
+specifies start and end times of the simulation, and the number of steps. It also
+configures which solvers are used.
+
+Only the model elements which are referenced from within the Study will be
+included in the simulation. In this case, everything in the `Main.Model` folder is
+part of the simulation.
