 **Warning**: If you are running Docker Toolbox instead of Docker Desktop (likely meaning you are running Windows 10 Home, not Professional) you will need to change your `.env` to reflect Docker running on a VM: 
 - `DATABASE_HOST`: The IP address Docker is running on. You can find this by running `docker-machine ip` but it's usually `192.168.99.100` instead of `localhost`
-- `DATABASE_URL_DEV`: This will need to be adjusted as well, for example `DATABASE_URL_DEV=postgres://postgres:.@localhost:5432/postgres` would become `DATABASE_URL_DEV=postgres://postgres:[email protected]:5432/postgres`
+- `DATABASE_URL`: This will need to be adjusted as well, for example `DATABASE_URL=postgres://postgres:.@localhost:5432/postgres` would become `DATABASE_URL=postgres://postgres:[email protected]:5432/postgres`
