  3. If the version upgrade is straight-foward with no specific upgrade-instructions run command one-step-smile-upgrade

     







    [Lottery] $ one-step-smile-upgrade

[info] smile build
[info] updating modules ...
[info] reloading ...

[Lottery] $

  4. To manually upgrade, run command steps-to-update-smile

     













    [Lottery] $ steps-to-update-smile
[info]
[info] 1. run 'update-to-current-smile-version'"
[info] 2. run 'smile'

[Lottery] $

    these steps could vary based on the project complexity, for example: there would be instructions to add/remove components/ libraries etc.
