-# Navigraph Navigation Data Interface in MSFS
+# Navigraph Navigation Data Interface for MSFS
 
-This is a barebones implementation to be able to download up-to-date Navigraph navigation data into MSFS (more specifically into the `work` folder of the aircraft).
+The Navigraph Navigation Data Interface enables developers to download and integrate navigation data from Navigraph directly into add-on aircraft in MSFS.
+
+
+## Key Features
+- Navigraph DFD Format: Leverage specialized support for Navigraph's DFD format, based on SQLite, which includes an SQL interface on the commbus for efficient data handling.
+- Javascript and WASM support: The navdata interface is accessible from both Javascript (Coherent) and WASM, providing flexibility for developers.
+- Supports updating of custom data formats.
+- Xbox compatibility: Works on PC and Xbox.
+- Persistence: All data is persisted in the `work` folder of the aircraft.
