+#### How to run docker-compose
+```
+docker compose up
+```
+
+#### Modiy file permissions for start.sh wait-for.sh for Control startup and shutdown order in Compose
+To make the api container run after by the postgres container, we have to use [`depends_on`](https://docs.docker.com/compose/startup-order/) and with `condition: service_healthy`
+By Legacy versions, besides the depends_on field, we need some script like [wait-for](https://github.com/mrako/wait-for), new version docker compose supported inside. Anyway, If we want to use some scipts, don't miss change scipts permissions.
