 ## Core Architecture
 
 ### Project-Oriented Design
 
-- Each project has a `pgx.toml` file at its root that defines the Postgres configuration
-- The project name is derived from the directory containing `pgx.toml`

 - Each project gets its own Docker container
 - State is tracked separately per instance to detect configuration drift
 
 ### Configuration Management

+The `pgd.toml` file stores:

 - `database_name`: Name of the database

 - `port`: Host port to bind (auto-selected from available ports)

 Key commands to implement:
-- `pgx init`: Create pgx.toml with auto-populated configuration
-- `pgx start`: Start the Postgres container for current project
-- `pgx stop`: Stop the running container
-- `pgx status`: Show instance status and detect drift
-- `pgx destroy`: Remove container and clean up
