 ## Documentation
 
-For more information on how to run the Shotgun/Unreal integration, please see the [support documentation](https://docs.unrealengine.com/en-us/Editor/Content/Using-Unreal-Engine-with-Autodesk-Shotgun).
+This repository is a part of the ShotGrid Pipeline Toolkit/Unreal integration and contains the source code for SG TK Unreal engine.
+
+The simplest way to add the ShotGrid Toolkit integration to Unreal is to start from the available standard Shotgrid Toolkit configurations:
+- Default2 SG TK configuration: https://github.com/ue4plugins/tk-config-unreal
+- Basic SG TK configuration: https://github.com/ue4plugins/tk-config-unrealbasic
+
+However, it is possible to manually add the integration to an existing SG TK configuration from the files provided in the `resources/config` folder.
+
+### Configuring the file system schema for a default2 base configuration
+If your SG TK configuration needs a file system schema, copy the files and directories from `resources/config/schema` under the `core/schema` folder of your existing configuration.
+```
+schema/
+└── project
+    ├── assets
+    │   └── asset_type
+    │       └── asset
+    │           └── step
+    │               ├── publish
+    │               │   └── fbx
+    │               │       └── placeholder
+    │               └── work
+    │                   └── fbx
+    │                       └── placeholder
+    └── sequences
+        └── sequence
+            └── editorial
+                └── placeholder
+```
+
+### Adding the SG TK Unreal components
+The `resources/config/unreal` folder contains all definitions needed by the integration
+```
+unreal/
+├── frameworks.yml
+├── settings
+│   ├── tk-multi-loader2.yml
+│   ├── tk-multi-publish2.yml
+│   ├── tk-multi-shotgunpanel.yml
+│   └── tk-unreal.yml
+├── templates.yml
+└── tk-unreal-location.yml
+```
+
+This folder should be copied to the `env/includes` folder of your existing configuration.
+
+Then the following files (or similar) need to be modified to add the Unreal integration:
+
+- *core/templates.yml*:
+  - add `include: ../env/includes/unreal/templates.yml`
+- *env/project.yml*: 
+  - add `- ./includes/unreal/settings/tk-unreal.yml` to *includes*
+  - add `tk-unreal: "@settings.tk-unreal.project"` to *engines*
+- *env/asset_step.yml*: 
+  - add `- ./includes/unreal/settings/tk-unreal.yml` to *includes*
+  - add `tk-unreal: "@settings.tk-unreal.asset_step"` to *engines*
+- *env/includes/settings/tk-maya.yml* or *env/includes/maya/asset_step.yml*:
+  - add `- ../unreal/settings/tk-multi-publish2.yml` to *includes*
+  - replace *tk-multi-publish2* asset step setting with: `tk-multi-publish2: "@settings.tk-multi-publish2.maya.asset_step.unreal"`
+- *env/includes/frameworks* or *env/includes/common/frameworks.yml*:
+  - add `include: unreal/frameworks.yml` 
+- *env/includes/settings/tk-desktop.yml* or *env/includes/desktop/project.yml*: 
+  - add "*Unreal*" to Creative Tools group.
