 # Assignment: Create A Multi-Service Multi-Node Web App
 
-## Goal: create networks, volumes, and services for a web-based "cats vs. dogs" voting app.
+## Goal: create networks, volumes, and services for a web-based "cats vs. dogs" voting app
 
 Here is a basic diagram of how the 5 services will work:
 
 ![diagram](./architecture.png)
 
-- All images are on Docker Hub, so you should use editor to craft your commands locally, then paste them into swarm shell (at least that's how I'd do it)
-- a `backend` and `frontend` overlay network are needed. Nothing different about them other than that backend will help protect database from the voting web app. (similar to how a VLAN setup might be in traditional architecture)
-- The database server should use a named volume for preserving data. Use the new `--mount` format to do this: `--mount type=volume,source=db-data,target=/var/lib/postgresql/data`
