+## Device Access
+
+The Device Access contains a for Celix adapted implementation of the OSGi Compendium Device Access Specification.
+
+## Properties
+    DRIVER_LOCATOR_PATH     Path to the directory containing the driver bundles, defaults to "drivers".
+                            The Driver Locator uses this path to find drivers.
+
+## CMake option
+    BUILD_DEVICE_ACCESS=ON
+
+## Using info
+
+If the Celix Device Access is installed, 'find_package(Celix)' will set:
+ - The `Celix::device_access_api` interface (i.e. headers only) library target
+ - The `Celix::device_manager` bundle target
+ - The `Celix::driver_locator` bundle target
