-## Running in development mode
+## Setup local database
+
+You can install PostgreSQL local https://www.postgresql.org/download/ or use Docker (see `postgres.yml`):
+```
+version: "3.2"
+services:
+  postgres:
+    image: postgres
+    environment:
+      POSTGRES_PASSWORD: pass
+    ports:
+      - 127.0.0.1:5432:5432
+    volumes:
+      - ./database:/var/lib/postgresql/data
+```
+
+To run it execute: `docker compose -f postgres.yml up -d` where `-d` is used for background run.
+If you have outdated version of docker, try use `docker-compose` instead of `docker compose` (https://docs.docker.com/compose/)
+
+## Running application in development mode
 
 To run application in development mode you need to run `npm run dev` command.
 It will start application with `nodemon` and restart it on any changes in source code.
