+Deploying this service is a short three step process. This assumes you already have a server with an OS of your choice that runs Node setup, if not refer to the [acquire a server](#acquire-a-server) section.

+1. Upload the files of the service to your server (you should be able to do this on your own)
+2. Start and daemonize the app with `pm2`
+3. Setup `nginx` as a reverse proxy to make your service publicy accessible
 
-This is what my `nginx` conf looks like in `/etc/nginx/sites-available/default`:
+## Start and deamonize the app
+
+Once all the files for this microservice are uploaded we'll use `pm2` to start and deamonize the app. This means that the app isn't bound to the terminal, and we'll also make `pm2` start the app when the server start.
+
+First run `npm install -g pm2` to get `pm2`, then run `pm2 start npm -- start`. This tells `pm2` to run `npm start` in the background.
+
+To make sure our service stays up even if the server reboots we run `pm2 startup ubuntu` (replace `ubuntu` with whatever OS you're using) and `pm2 save`.
+
+## Set up `nginx`
+
+Get `nginx` by running `sudo apt-get install nginx`, then configure it to reroute all incoming requests to the server to our server.
+
+Delete the default site from nginx by running `sudo rm /etc/nginx/sites-enabled/default`, then create a new one by running `sudo touch /etc/nginx/sites-enabled/<yoursite>`. (replace `<yoursite>` with your site name)
+
+We want to reroute all requests for any path that come in to our service, so edit the `/etc/nginx/sites-enabled/<yoursite>` file to look like this:
 
 ```nginx
 server {
-        listen 80;
-        server_name yourserver.com;
-
-        location ~^.*$ {
-                proxy_set_header X-Real-IP  $remote_addr;
-                proxy_set_header X-Forwarded-For $remote_addr;
-                proxy_set_header Host $host;
-                proxy_pass http://localhost:3000;
-        }
+  listen 80;
+  server_name yoursite.com;
+
+  location ~^.*$ {
+    proxy_set_header X-Real-IP  $remote_addr;
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header Host $host;
+    proxy_pass http://localhost:3000;
+  }
 }
 ```
