# Project Management
After you understand the app model, the next layer is operating the project itself.
## Main areas
- Settings
- credentials
- database connections
- files
- git
- session / MCP access
- interface surfaces in Studio
## What matters in practice
- your project repo is the working source of truth
- git tracks the project workspace under `repo/`
- settings and credentials shape how the project can run
- Studio gives a unified surface for building, reviewing, and operating the project
Credentials are encrypted at rest under an instance key kept outside the
database. Where that key lives, what happens when it is lost, and how to rotate
it: `help("guide/credential-encryption")`.
