-## API & Integration
+## Integration
 
-Developers can integrate with the Meshtastic Android app using our published API library via **JitPack**. This allows third-party applications (like the ATAK plugin) to communicate with the mesh service via AIDL.
-
-For detailed integration instructions, see [core/api/README.md](core/api/README.md).
-
-Additionally, the app includes a built-in **Local TAK Server** feature that can be enabled in settings. This runs a local TCP server on port 8089 to allow ATAK clients to connect directly and route their traffic over the mesh.
