 This will create a site at http://localhost:8080. The blog can be found at http://localhost:8080/blog/ and you can login at http://localhost:8080/blog/admin/. The first time you visit the login a user will be created and the details printed to the console.

+**Note**: If you receive an error such as "Thread 1: Fatal error: Error raised at top level...", then it is likely you are already running an instance of PostgreSQL on your machine. To try and resolve:
+
+```
+./bin/stopDB.sh               # will stop your existing docker instance if running
+lsof -i :5432                 # will show you existing processes running postgres
+brew services stop postgresql # will stop postgresql if homebrew is running it
+./bin/setupDB.sh              # restarts db for this example
