+libdnnl for Unikraft
+===================
+This is a port of Intel's DNNL to Unikraft. The port has a number of
+dependencies. To meet them, ensure that you have the following libs
+added to your LIBS variable in your app's Makefile:
+                                               
+ * CXX standard library, e.g. `libunwind`, `compiler-rt`, `libcxxabi`,
+  `libcxx`
+  * `libc`, e.g. `newlib`
+  * an intrinsics package, e.g., `intel-intrinsics` or `arm-intrinsics`
+  
+Please refer to the `README.md` as well as the documentation in the `doc/`
+subdirectory of the main unikraft repository.
