need to show simple ways to share a workflow and error in compute tool when use a expression c8+1

I think it is important to mention in the introductory tutorial that the beta version allows to share in a public and much simpler way the histories,workflow.


furthermore, when i had to add the expression c8+1 by running the tool "compute a expression in every row" it did not work.
so i had to replace that step by using the tool "add column" which is from version 1.0.0.0 which is old. i consider that reviewing and make some changes in the introduction resourcers is important.
