 ## Architecture
 
-LetsGo employs a fully containerized, microservices-oriented architecture. Nginx serves as the entry point, routing requests to the Next.js frontend or the Go backend. The Go backend interacts with PostgreSQL for persistent data and Redis for real-time messaging and caching. All components are defined and orchestrated via Docker Compose.
