+If you have never participated in an election and written up a nomination
+before here are a few tips to help you:
+
+* One purpose of the nomination text is to help the community to know you
+  better and understand why you are running for the position
+* Technical background and skills that you feel relevant for the position
+  are good to mention
+* Summarizing your involvement with the project will help to show what areas
+  you are active in and what your experience is with the project and community
+* Listing responsibilities you would take and actions you would drive will
+  help the community to understand how you can fit into the TSC group if you
+  get elected
+* There is no perfect nomination, make sure you include all talking points
+  you would be interested to read in others'
+* Don't forget to send the text to the starlingx-discuss mailing list as well
+* For examples and inspiration you can look into the election candidacy folder
