+  ### Chat XDK now available on public package registries
+
+  The [Chat XDK](/xchat/xchat-xdk) is now published to public package registries, so you can install it with your language's standard package manager — no more building from source.
+
+  - **Python:** `pip install chatxdk` (imports as `chat_xdk`)
+  - **TypeScript:** `npm install @xdevplatform/chat-xdk` (optional `juicebox-sdk` peer dependency for secure key backup)
+  - **C#:** `dotnet add package XDevPlatform.ChatXdk` — self-contained with bundled native libraries for macOS, Linux, and Windows
+  - **Java:** available on Maven Central as `com.x:chatxdk` — the jar bundles the native libraries, so no `jna.library.path` setup is needed
+  - **Rust:** `chat-xdk-core` is not yet on crates.io — use the git dependency shown in the [reference](/xchat/xchat-xdk)
+
+  See [Chat XDK Reference](/xchat/xchat-xdk) and [Getting started](/xchat/getting-started) for install snippets and quick starts.
