+# Development
+
+The easiest is to obtain VM from Proxmox cluster with public IP address.
+To run development instance:
+
+```
+docker-compose -f docker-compose.dev.yml up --build
+```
+
+On kdoorpi override `KDOORPI_API_ALLOWED`, `KDOORPI_API_LONGPOLL` environment variables
+to redirect requests to your dev instance.
+
 # Deploying
 
+To deploy in prod adjust `DOORBOY_SECRET`, `MONGO_URI` in `.env` and proceed to launch:
