This is our initial port of pthread-embedded to Unikraft as external
library. For now you need newlib to make it work. When adding the
library in the dependency list, pthread-embedded should stay before
newlib (e.g. ...:$(UK_LIBS)/pthread-embedded:$(UK_LIBS)/newlib.git:...).

 pthread-embedded for Unikraft
 =============================
 
+This is the port of pthread-embedded for Unikraft as external library. You will
+need newlib to make it work. When adding the library in the dependency list,
+pthread-embedded should stay before newlib, e.g.:
+
+ `...:$(UK_LIBS)/pthread-embedded:$(UK_LIBS)/newlib:...`
+
+For running the unit tests, enable the 'Build unit tests' option in the
+configuration menu and call the `pte_test_main()` function in your main
+application.
+
 Please refer to the `README.md` as well as the documentation in the `doc/`
 subdirectory of the main unikraft repository.
