Stack lifecycle flow chart

[kke]

https://kontena.io/docs/using-kontena/stacks.html needs some kind of stack lifecycle flowchart, such as:

       [Kontena Stack YAML] -<<<------+
                |                     |
 +-yes- < Needs to be built? > -no-+  |
 |                                 |  |
 +- [ Build ]    +-----------------+  |
         |       |                    |
      [ Push ]   |                    |
         |       |                    |
         +-----+ |                    |
               | |                    |
            [ Install ]               |
                 |                    |
             [ Deploy ]               |
                 |                    |
            [ Upgrade ] ->>>----------+

but prettier.

(also I think the repetition of the word Kontena Stack in the chapter list does not look pleasant and most of the chapters are oneliners + command example.)
