 Change configuration in docker-compose.yml to update passwords for MySQL/RabbitMQ.
 Both passwords in the `postal` service, `mysql` service and `rabbitmq` service have to be changed.
 
-Then, start postal by running
+Then, begin by following the directions at https://github.com/atech/postal/wiki/Installation#initialize-database--assets.
+Postal can be accessed by checking the section below. Note that "intialize-config" is already run for you, as the database parameters need to be configured before the postal tool can be used.
+
+After configuration is done, run the following to bring the container up.
 ```
 docker-compose up -d
 ```
+### Using the `postal` tool.
+To use the `postal` tool, simply run
+```
+docker-compose run postal <parameter>
+```
+For example, the following command runs `postal initialize` inside the container.
+```
+docker-compose run postal initialize
+```
 
-Default password is avaliable at https://github.com/atech/postal/wiki/Installation#accessing-the-web-interface
-
-### Configuration
-Configuration is located at data/postal after the first start. Note that non-config files (i.e. files in https://github.com/atech/postal/tree/master/config) will be overwritten each time the container starts up. See https://github.com/atech/postal/blob/master/config/postal.defaults.yml for all possible configuration options
+### Migrations
+See https://github.com/atech/postal/wiki/Upgrading.
 
 Be sure to do some port mappings to allow your SMTP server and HTTP(s) server to be accessed. I suggest simply port mapping the SMTP server and using [jwilder/nginx-proxy](https://github.com/jwilder/nginx-proxy) to proxy the HTTP server.
