What is the best way for a team to collaborate on a slack bolt app?

Question

Hello, I'm currently working on a slack app using boltjs (multiworkspace and http events, not in socket mode), I did not use slack cli or started from a template. I'm in the process of making a get started readme that would allow another developper to get the app up and running quickly. So far it seemed to require creating the app from manifest on slack dev dashboard. I then took a dive into slack cli and I'm trying to see if it could accelerate the dev workflow, the two biggest things I'm trying to improve are:

1. Allowing a dev to get the app running as quickly as possible on his machine
2. Possibly setting up a sandbox environment

Thanks for your help

• I've read and understood the Contributing guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.
• I've searched for any related issues and avoided creating a duplicate issue.

Start with the proposed get-started README and the Slack CLI app-manifest workflow described in the issue. Document a reproducible setup for another developer and clarify whether the CLI can support a shared sandbox environment; no specific source files or tests are identified.
