Using Buidler... clarity on adding and integrating apps/templates

I can understand the tutorial at a basic level. I felt good after I was able to create the tutorial counter app. However, I am unclear on the approach and the basic commands to even start trying to integrate/add existing apps into my work (finance, voting, etc). Additional clarity, an example of how to integrate and use the buidler scripts towards this goal would be helpful. I am trying to create a “simple” membership organization with voting and payment to become member. I also read through this article —the Finance App Using Vault Link didn’t work

The existing boilerplates seems limited and I saw this script for Tokenwrapper but not sure how to implement it.

I thought I would be able to use the monorepo of Aragon Apps somehow

Bump. Willing to clarify if necessary.
