+### Docker
+1. follow the [instructions](https://docs.docker.com/desktop/mac/install/) to install docker.
+2. open terminal and run: `docker pull postgres`
+   
+3. run `make init_docker` if you have not run before. You can find out the running container by run `docker ps`
+```
+CONTAINER ID   IMAGE      COMMAND                  CREATED          STATUS          PORTS                                       NAMES
+bfcdd6369e89   postgres   "docker-entrypoint.s…"   19 minutes ago   Up 19 minutes   0.0.0.0:5433->5432/tcp, :::5433->5432/tcp   brave_bassi
+```
+
+4. run `make init_database`. It will create the database on the remote specified by DATABASE_URL. You can connect you database using 
+pgAdmin. 
+   
+
+![img_2.png](img_2.png)
+
+The information you enter must be the same as the `make init_docker`. e.g.
+```
+export DB_USER=postgres
+export DB_PASSWORD=password
+export DB_NAME=flowy
+export DB_PORT=5433
+```
