+
+## Environment Setup
+
+In order to use MetaHuman DNA Calibration in your scripts, you need to:
+- have Python3 installed, see [note](README.md#external-software-dependencies),
+- add MetaHuman DNA Calibration location to `MAYA_MODULE_PATH` system variable (if you want to use MetaHuman DNA Calibration in Maya)
+
+
+If you plan to run the script from command line:
 
+- in case of Maya's interpreter (mayapy) you will have to initialize maya with:
+
+```python
+import maya.standalone 
+maya.standalone.initialize()
+```
+
+- in case of python interpreter you will have to add the following on top of your script: 
+```python
+from os import path as ospath
+from sys import path as syspath
+from sys import platform
+
+ROOT_DIR = f"{ospath.dirname(ospath.abspath(__file__))}/..".replace("\\", "/")
+MAYA_VERSION = "2022"  # or 2023
+ROOT_LIB_DIR = f"{ROOT_DIR}/lib/Maya{MAYA_VERSION}"
+if platform == "win32":
+    LIB_DIR = f"{ROOT_LIB_DIR}/windows"
+elif platform == "linux":
+    LIB_DIR = f"{ROOT_LIB_DIR}/linux"
+else:
+    raise OSError(
+        "OS not supported, please compile dependencies and add value to LIB_DIR"
+    )
+
+# Adds directories to path
+syspath.insert(0, ROOT_DIR)
+syspath.insert(0, LIB_DIR)
+```
+
+NOTE: 
+If running on Linux, please make sure to append the LD_LIBRARY_PATH with absolute path to the `lib/Maya2022/linux` or `lib/Maya2023/linux` directory before running the example: 
+ - `export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path-to-lib-linux-dir>`
 
 ## DNAViewer
 With DNAViewer, you can:
 - Create functional rigs for Maya.
 - Export FBX files.
 - Read internal parts of DNA files.
 
-DNAViewer can be used in `mayapy` (Maya's Python interpreter) or in Maya 2022, except [Propagating changes from Maya scene to dna](/examples/dna_viewer_grab_changes_from_scene_and_propagate_to_dna.py) which can be used just in Maya.

 # Examples
 Several Python examples are provided for reference and can be found in the **examples'** folder:
 - [Showcase a few commands](/examples/dnacalib_demo.py)
 - [Rename a joint](/examples/dnacalib_rename_joint_demo.py)
 - [Create a small DNA from scratch](/examples/dna_demo.py)
+- [Read binary DNA and write it in a human readable format](/examples/dna_binary_to_json_demo.py)
 - [Create a new DNA from an existing one by extracting specific LODs](/examples/dnacalib_lod_demo.py)
 - [Remove a joint](/examples/dnacalib_remove_joint.py)
 - [Clear blend shape data](/examples/dnacalib_clear_blend_shapes.py)
 - [Subtract values from neutral mesh](/examples/dnacalib_neutral_mesh_subtract.py)
 - [Simple UI in Maya](examples/dna_viewer_run_in_maya.py) and some [documentation](docs/dna_viewer.md#usage-in-maya) for it
-- [Generate rig and export FBX per LOD](examples/dna_viewer_demo.py)

+Note: Examples are grouped in three groups: DNA, DNACalib, and DNAViewer. These names are embedded as prefixes: dna_, dnacalib_, and dna_viewer_.   
+
 ## Example DNA files
 [Two demo DNA files](data/dna) are provided for easier testing of this tool. Any DNA generated with [MetaHumanCreator](https://www.unrealengine.com/en-US/metahuman)
 should work.
 
 # Notes
 If a user runs examples in Maya 2022, the value for `ROOT_DIR` should be changed and absolute paths must be used, 
-eg. `c:/dna_calibration` in Windows or `/home/user/dna_calibration` in Linux. Important: Use `/` (forward slash), Maya uses forward slashes in path.
+e.g. `c:/MetaHuman-DNA-Calibration` in Windows or `/home/user/MetaHuman-DNA-Calibration` in Linux. Important: Use `/` (forward slash), Maya uses forward slashes in path.
