Hi @denyeart and @bestbeforetoday

I would like to have you reviewed with current WIP part of code as if I am moving on, this pr will be too large to review. Hence I make current implementation with lifecycle install as an example for how it's going to be like.

Please let me know for your review comments.

Regards Sam
