+# BLE API Cordio Link Layer Implementation
+
+The BLE API Cordio link layer implementation allows Cordio licensee to easily
+deliver a complete and up to date implementation of mbed BLE to their customers
+using mbed OS.
+
+The library a consists of the controller HCI, Bluetooth 5 compliant link layer
+protocol core, scheduler, baseband porting layer and a portable software
+foundation.
+
+To deliver a BLE port, vendors simply have to provide an HCI driver tailored
+for the BLE module present on the board they want to support.
+
+## Source Organization
+
+The root contains the binary distribution `libcordio_stack.a` of the library and
+the folders contain the public headers to interface with it.
+
+* `controller`: HCI Controller headers
+* `platform`: Platform headers
+
+
+## Library information
