 - **server**: Node.js app, utilizing [Express](https://expressjs.com). The server provides various microservices, like remote file checking.

+This means you need to connect with your MetaMask to the Nile network too. To do this:
+
+1. select Custom RPC in the network dropdown in MetaMask
+2. under New Network, enter `https://nile.dev-ocean.com` as the custom RPC URL
+3. Hit _Save_, and you’re now connected to Nile
