+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the

+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.

-Our Team is developing a Speckle plugin and interoperability transport schema for UE4. Our goal is to enable Revit/Dynamo and Rhino/Grasshopper to send + receive geometry to UE4 for visualization. Our current priority is to establish and release a data sender (TO UE4). We’re also working on receiver methods, however our initial focus  is on Rhino/Grasshopper to UE4 translation and the attachment of UE4-specific metadata to the core JSON ‘blobs’ in transport.
-
-In this repository you will find the source code, assets and project settings of the SpeckleUnreal plugin for Unreal Engine app development (Unreal Engine 4.25.1 or newer recommended).

-
-## NOTICE
-
-* Tested on Windows and MacOS and Linux.
-* Only displays meshes. Breps are converted using their display values.
-* Does not use the Speckle Kit workflow as conversions all happen in C++. 
-
-## How To Install
+Speckle makes integrating Unreal Engine with your 3D workflows even easier. </br>
+This plugin connects Unreal Engine to Speckle, allowing you to receive your versioned 3D data from Speckle inside Unreal Engine,
+enabling interoperable collaboration between Unreal and other Speckle connectors (Revit, Rhino, Blender, Sketchup, Unity, AutoCAD, [and more!](https://speckle.systems/features/connectors/))
 
 
-1. Clone the repository or download it as a zip file.
-2. Navigate to `SpeckleUnrealProject` > `Plugins` and copy the `SpeckleUnreal` folder
-3. Paste the folder into your Unreal project under `YourUnrealProjectFolder` > `Plugins` (Create a `Plugins` folder if you don't already have one).
-4. Reopen your project.

-We will eventually look to distributing the plugin officially on the Unreal Engine Marketplace but for now you'll need to install the plugin manually like this.
+
+Checkout our dedicated [Tutorials and Docs](https://speckle.systems/tag/unreal/).
+
+If you are enjoying using Speckle, don't forget to ⭐ our [GitHub repositories](https://github.com/specklesystems),
+and [join our community forum](https://speckle.community/) where you can post any questions, suggestions, and discuss exciting projects!
+
+## Notice
+
+We officially support Unreal Engine 4.27, 5.0, 5.1, 5.2
+
+**Features**:
+- [Receiving Speckle geometry as Actors in editor and standalone runtime](https://speckle.systems/tutorials/getting-started-with-speckle-for-unreal/).
+- [Material override/substitiution](https://speckle.guide/user/unreal.html#material-converter).
+- [Blueprint nodes for receiving and converting objects](https://speckle.guide/user/unreal.html#usage-blueprint).
+- [Blueprint nodes for fetching stream/branch/commit/user details](https://speckle.systems/tutorials/unreal-engine-blueprint-nodes-fetch-stream-branch-commit-info-and-more/).
+- [Ability to write/extend custom conversion functions in C++/BP](https://speckle.systems/tutorials/unreal-developing-custom-conversion-logic/).
+
+**Supported Conversions**:
+
+ Speckle Type |  | Native Type |
+| ---: | :---: | :--- |
+| [`Objects.Geometry.Mesh`](https://github.com/specklesystems/speckle-sharp/blob/main/Objects/Objects/Geometry/Mesh.cs) | → | [Static Mesh Component](https://docs.unrealengine.com/4.27/en-US/API/Runtime/Engine/Components/UStaticMeshComponent/) /<br/> [Procedural Mesh Component](https://docs.unrealengine.com/4.27/en-US/API/Plugins/ProceduralMeshComponent/UProceduralMeshComponent/) |
+| [`Objects.Geometry.PointCloud`](https://github.com/specklesystems/speckle-sharp/blob/main/Objects/Objects/Geometry/Pointcloud.cs) | → | [LiDAR Point Cloud](https://docs.unrealengine.com/4.27/en-US/WorkingWithContent/LidarPointCloudPlugin/LidarPointCloudPluginReference/) |
+| [`Objects.Other.Instance`](https://github.com/specklesystems/speckle-sharp/blob/main/Objects/Objects/Other/Instance.cs) | → | Actor with Transform |
+| [`Objects.BuiltElements.View`](https://github.com/specklesystems/speckle-sharp/blob/main/Objects/Objects/BuiltElements/View.cs) | → | [Camera](https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Framework/Camera/) |
+
+**Supported platforms**: Windows, Linux, MacOS
+*Other platforms may work, but currently untested*.
+
+
+**Limitations**:
+- Currently no support for sending Unreal geometry to Speckle.
+- Does not use the .NET or Python SDK, or the Speckle Kit based workflow, all code is in native C++/BP.
+- Does not use our shared [Desktop UI 2](https://speckle.guide/user/ui2.html), only a simple editor UI is currently provided.
+- Does not fetch [accounts from Speckle Manager](https://speckle.guide/user/manager.html#logging-in-adding-accounts), you must generate a [personal access token (auth token)](https://speckle.guide/dev/tokens.html#personal-access-tokens) to receive non-public streams.
+
+## How to install
+
+**Speckle for Unreal Engine** can be installed through the [Unreal Engine Marketplace](https://www.unrealengine.com/marketplace/en-US/product/speckle-for-unreal-engine).
 
 ---
 
-## Roadmap
+Alternatively, developers may prefer to install manually.
+1. Git clone [this repo](https://github.com/specklesystems/speckle-unreal) (or download and extract the [archive zip](https://github.com/specklesystems/speckle-unreal/archive/refs/heads/main.zip)) into your project's `Plugins` directory (created as needed)
+2. Open/Restart your Unreal project. This will build the plugin for your environment.
 
-> Roadmap is subject to change. Last reviewed 10th of July 2020.
+See our [docs](https://speckle.guide/user/unreal.html) for usage instructions.
