 # GDSiON
 
-**GDSiON** is a software synthesizer library implemented as a GDExtension for the [Godot engine](https://godotengine.org/). It is originally based on [SiON](https://github.com/keim/SiON), a software synthesizer for the Flash and Adobe AIR platform, and just like its predecessor _GDSiON_ is self-sufficient and allows for easy dynamic sound generation. You can drive the process using Music Macro Language (MML) notation or direct API calls.

+## How can I help the project?
+
+First and foremost, using _GDSiON_ and reporting problems is already a great help! Please, don't hesitate to submit reports of any stability issues, incorrect behavior, or missing API access for some classes and functions.
 
-## How can I help?
+If you have a functional suggestion, feel free to submit it as well! But please do be patient. Authors of this project are not very well versed in audio and music production. It may take a bit of time to understand and address your needs.

+### Contributions and pull-requests
 
-At the current stage the project is still considered to be incomplete, and efforts are made to port the remaining classes and systems to the new platform. As a developer and a potential contributor you can assist in these efforts. Please try to get in touch first if you want to work on porting any of the missing parts. Existing FIXMEs and TODOs are open for everyone.
+At this stage the project is considered feature complete. The main focus right now is on testing and improving the general state of it. You can help the efforts by creating unit tests, enhancing CI with additional checks and code style validation, writing documentation, etc. For code contributions, the biggest target is addressing memory management issues. There is also a number of TODOs and FIXMEs already present in the codebase which can be a good starting point for a quality PR!
 
-We would also appreciate assistance with setting up the CI, introducing tests, code style enforcement, writing documentation, etc. Code style, code quality, and architecture/design suggestions are welcomed as well.
+If you want to work on a new feature, or perhaps have an idea for a better code architecture and design, please try to get in touch first. Such contributions are ultimately welcome, however the project is still going through its early days, so changes must be considered carefully.
 
-If you have a functional suggestion, feel free to submit it! But please do be patient. Authors of this project are not very well versed in audio production and currently aim to get what already exists in the original SiON project working and available in this extension. It may take a bit of time to understand and address your needs.
+There are also a few features that didn't make it into this initial release, namely MIDI support and Godot audio stream support for input and sampling. These are areas worth of exploration as a target for a future release of the library.
