+    [Documentation]   Onboards ("creates") a NF Package into OSM.
+    ...               - Parameters:
+    ...                 - vnfd_pkg: Name (and location) of the NF Package
+    ...                 - overrides (optional): String with options to override the EPA and/or interface properties of the Package.
+    ...                                        This is very useful to allow to deploy e.g. non-EPA packages in EPA VIMs (or vice-versa).
+    ...                                        Valid strings are the same as in the command. E.g.:
+    ...                                        - `--override-epa`: adds EPA attributes to all VDUs.
+    ...                                        - `--override-nonepa`: removes all EPA attributes from all VDUs.
+    ...                                        - `--override-paravirt`: converts all interfaces to `PARAVIRT`. This one can be combined with
+    ...                                           the others above (e.g. '--override-nonepa --override-paravirt').
+    ...               - Relevant environment variables:
+    ...                  - OVERRIDES: If the environment variable "OVERRIDES" exists, it prevails over the value in the argument.
+    ...                               This is often more convenient to enforce the same behaviour for every test run in a given VIM.
