+[Documentation is available here](https://godotsteam.com/).  You can also check out the Search Help section inside Godot Engine.  [To start, try checking out our tutorial on initializing Steam.](https://godotsteam.com/tutorials/initializing/)  There are additional tutorials, with more in the works.  You can also [check out additional Godot and Steam related videos, text, additional tools, plug-ins, etc. here.](https://godotsteam.com/resources/external/)
+
+Feel free to chat with us about GodotSteam or ask for assistance on the [Stoat server](https://stt.gg/9DxQ3Dcd) or [IRC on Libera Chat](irc://irc.libera.chat/#godotsteam).

+
+
+Current Build
+---
+You can [download pre-compiled versions of this repo here](https://codeberg.org/godotsteam/godotsteam/releases).
+
+**Version 4.17.1 Changes**
+
+- Changed: SCsub and config.py for ARM64 and Android
+- Fixed: potential crash in disconnect_peer; thanks to ***bearlikelion***
+
+[You can read more change-logs here](https://godotsteam.com/changelog/gdextension/).
+
+
+Compatibility
+---
+While rare, sometimes Steamworks SDK updates will break compatilibity with older GodotSteam versions. Any compatability breaks are noted below.  Newer API files (dll, so, dylib) _should_ still work for older versions.
+
+Steamworks SDK Version | GodotSteam Version
+---|---
+1.63 or newer | 4.17
+1.62 | 4.14 or 4.16.2
+1.61 | 4.12 to 4.13
+1.60 | 4.6 to 4.11
+1.59 | 4.6 to 4.8
+1.58a or older | 4.5.4 or older
+
+Versions of GodotSteam that have compatibility breaks introduced.
+
+GodotSteam Version | Broken Compatibility
+---|---
+4.8 | Networking identity system removed, replaced with Steam IDs
+4.9 | sendMessages returns an Array
+4.11 | setLeaderboardDetailsMax removed
+4.13 | getItemDefinitionProperty return a dictionary, html_needs_paint key 'bgra' changed to 'rbga'
+4.14 | Removed first argument for stat request in steamInit and steamInitEx, steamInit returns intended bool value
+4.16 | Variety of small break points, refer to [4.16 changelog for details](https://godotsteam.com/changelog/godot4/)
+4.17 | Windows projects using Steam SDK 1.63 are meant to work with Proton 11 or Experimental on Linux / Steam Deck.
+
+
+Known Issues
+---
+- GDExtension for 4.4 is **not** compatible with 4.3.x or lower. Please check the versions you are using.
+- Overlay will not work in the editor but will work in export projects when uploaded to Steam.  This seems to a limitation with Vulkan currently.
+
+
+Quick How-To
+---
+For complete instructions on how to build the GDExtension version of GodotSteam, [please refer to our documentation's 'How-To GDExtension' section.](https://godotsteam.com/howto/gdextension/) It will have the most up-to-date information.
+
+Alternatively, you can just [download the pre-compiled versions in our Releases section](https://codeberg.org/godotsteam/godotsteam/releases) or [from the Godot Asset Library](https://godotengine.org/asset-library/asset/2445) and skip compiling it yourself!
+
+
+Usage
+---
+Do not use the GDExtension version of GodotSteam with any of the module versions whether it be our pre-compiled versions or ones you compile.  They are not compatible with each other.
+
+When exporting with the GDExtension version, please use the normal Godot Engine templates instead of our GodotSteam templates or you will have a lot of issues.
