-This repository is for showcasing the new GDExtension system in Godot 4.
-The C++ code is from the [Custom modules example](https://docs.godotengine.org/en/latest/development/cpp/custom_modules_in_cpp.html "Click to get to the docs") of the Godot docs.
-
-----> **Feel free to use this repository as a template for your GDExtensions**
-
-## :tada: Using the extension
-After compiling the extension succesfully, you can now use the Summator Class inside Godot
-```gdscript
-func _ready() -> void:
-	var s = Summator.new()
-	s.add(10)
-	s.add(20)
-	s.add(30)
-	print(s.get_total())
-        # outputs 60 in the console
-	s.reset()
-```
+# TiltFiveGodot
 
-## 🔢 Versioning
-This repository is being updated regularly to work with the latest beta release of the master (4.0) branch. If you can't compile the extension, please open an issue.
+TiltFiveGodot is **GDNative** extension for the Godot engine to connect to the [Tilt Five](https://www.tiltfive.com/) 
+system. It implements Godot's **ARVRinterface** and has GDNative class called TiltFiveManager for scripts to connect 
+glasses and handle connection events.
 
-----> **Most Recent Update: Godot 4 RC 4 working**
+## Platforms
 
-## ❓ What? How? Why?
-If you are not sure what each file in this project does or if you want to know in detail: I wrote a blog post about the purpose of each file on [my Ko-Fi page](https://ko-fi.com/post/GDExtension--Godot-SUPERCHARGED--How-to-get-star-Z8Z4GLUSE).
+Currently only Windows 10/11 is supported because that is the only platform supported by Tilt Five. T5 linux support
+is supposed to come at some point in the future and support for that platform will revisited when it becomes available. 
 
-## Alternative templates
-If you want to work with the latest master and godot-cpp version, check out this [GDExtension template by Nathan Franke](https://github.com/nathanfranke/gdextension).
-If you are more used to CMake than Scons you can use [this template here by asmalone](https://github.com/asmaloney/GDExtensionTemplate)
+## Build
 
+### Prerequisites
 
-## ℹ️ Contributing
-If you can't compile the extension, please open an issue with the error log in your terminal and/or the error log in the editor (if you can't run the example scene).
+Make sure you have [SCons](https://scons.org/) installed and a C++20 compatible 
+compiler like Visual C++ 2022. 
 
-PRs for improvements are very welcome!
+After cloning this repository be sure to get and build the submodules
 
-## ⚙️ Building the extension
+```
+git submodule init
+git submodule update
+cd godot-cpp
+git submodule init
+git submodule update
+scons
+scons target=release
+```
 
-### VSCode Compilation (only applicable if you are using VSCode as your code editor)
-For the initial build you can run the vscode task `initial-build-extension`. This compiles both godot-cpp and the extension. For all subsequent builds, you only need to run the task `build-extension`.
+### Building the extension
 
-### Manual Compilation
+Scons should be run from an environment that has the Microsoft x64 development tools setup.
 
-To compile the extension you need to follow these steps:
+> `scons target=[debug | release]` Build the shared library. Result is in `build\bin`
 
-0. Click on the green "Use this template" button to generate the repository for you
+> `scons example target=[debug | release]` Copy build products to the `example\addons\tilt-five`
 
-1. Clone the extension recursively from this repository
-```bash
-# --recursive to automatically load the submodule godot-cpp
-# The git adress can be found under the green "Code" dropdown menu
-git clone --recursive (--GITHUB ADRESS--)
-```
+> `scons zip target=[debug | release]` Create a zip archive of `example\addons`
 
-2. Make sure you are on the right commit of the godot-cpp repository
-```bash
-git status
-# this show's you the commit. Make sure that it is released to a similar/the same time as the master branch (especially during the beta)
-```
-To make sure you have the right commit, here the [link to the pinned updated issue with the commit hashes](https://github.com/godotengine/godot-cpp/issues/874)
+Note that currently due to bugs the zip archive is not compatible with godot's import function.
 
-3. Make sure you are in the top level of the repository so `pwd` returns the following
-```bash
-pwd
-.../GDExtensionSummator
-```
+## Basic usage 
 
-4. Go inside the godot-cpp folder
-```bash
-cd godot-cpp
-```
+After building the example you should be able to open the Godot project in the example directory
+and run the default scene.
 
-5. Compile godot-cpp and generate the bindings (only needed once when starting development or when there is an update of the submodule)
-```bash
-scons target=template_debug
-# OR simpler (the above is the default configuration):
-scons 
+If you want to use the extension in your own project follow these steps.
 
-# For beta 2 and earlier:
-scons target=debug generate_bindings=yes
-```
+1) Copy `example\addons` to your own projects root directory. 
 
-6. Go back to the top level of the directory
-```bash
-cd ..
-```
+2) From `addons\tilt-five\scenes` load the `t5-scene` and run. 
 
-7. Compile the extension
-```bash
-scons target=template_debug
-# OR simpler (the above is the default configuration):
-scons
+3) From here you should be able to follow documentation for usage of Godot's AR/VR system.
 
-# For beta 2 and earlier:
-scons target=debug
-```
+## Dependencies
+
+- Uses the godot-cpp headers
+- Uses the Tilt Five NDK
+
+## TODO
+
+- Better docs and examples
+
+## Acknowledgments
+
+This was written by referring a lot to [GodotVR](https://github.com/GodotVR) code and reading 
+[Godot's](https://github.com/godotengine/godot) source code.
