+# 1) first jump into image (make sure you are in the directory where Makefile is):
+#    > docker run -it -v ${PWD}:/usr/src/exercise_1 -w /usr/src/exercise_1/ hpcimage
+# 2) Clean binaries first **important**
+#    > make clean
+# 3) for v4 cilk for example:
+#    > make csal_v4_cilk
+# 4) run executables from `out/`
