+
+From the backend directory, you have a few options:
+
+Option 1: Single command (both API + poller)
+cd /Users/kjannette/workspace/koin_ping_0.2.0/backendmake dev-all
+
+Option 2: Two separate terminals
+Terminal 1 (API server):
+cd /Users/kjannette/workspace/koin_ping_0.2.0/backend go run ./cmd/api
+Terminal 2 (Poller):
+cd /Users/kjannette/workspace/koin_ping_0.2.0/backend go run ./cmd/poller
+
+make run — Builds and runs the API server.
+make dev — Runs the API server with auto-reload via air (falls back to go run if air isn't installed).
+make poller — Builds and runs the poller.
+make poller-dev — Runs the poller with auto-reload.
+make dev-all — Runs both the API and poller concurrently.
