+6. build the project using Qt Creator
+
+If the Project does not build at this point, you might need to add additional Paths/Libs, because brew does not install openssl and boost in the common path. You can get their path using
+
+`brew info openssl`
+`brew info boost`
+
+The lines which you need to add to your project file should look similar to this
