-## 7. Install the Admin Control Panel (optional)
+## 7. Enable the systemd service
+
+If you don't like manually starting GoToSocial on every boot you might want to create a systemd service that does that for you.
+First create a new user and group for your gotosocial installation.
+
+```bash
+sudo useradd -r gotosocial
+sudo groupadd gotosocial
+sudo usermod -a -G gotosocial gotosocial
+```
+
+Then make them the owner of your GoToSocial installation since they will need to read and write in it.
+
+```bash
+sudo chown -R gotosocial:gotosocial /gotosocial
+```
+
+You can find a `gotosocial.service` file in the `example` folder on [github](https://raw.githubusercontent.com/superseriousbusiness/gotosocial/main/example/gotosocial.service) or your installation.
+Copy it to `/etc/systemd/system/gotosocial.service`.
+
+```bash
+sudo cp /gotosocial/example/gotosocial.service /etc/systemd/system/
+```
+
+Then use `sudoedit /etc/systemd/system/gotosocial.service` to change the `ExecStart=` and `WorkingDirectory=` lines according to your installation.
+If you have been following this guide word for word the defaults should be fine.
+After you're done enable the service.
+
+```bash
+sudo systemctl enable --now gotosocial.service
+```
+
+## 8. Install the Admin Control Panel (optional)
 
 At some point you'll likely want to do things like change instance information, and block domains you don't want to interact with. See the [admin panel](../admin/admin_panel.md) instructions for this.
+
+## 9. Reverse proxy with nginx (optional)
+
+If you want to run other webservers on port 433 or simply want to add an additional layer of security you might want to [use nginx as a reverse proxy](./nginx.md).

+# Reverse proxy with nginx
+
+## Requirements
+
+For this you will need certbot, the certbot nginx plugin and of course nginx.
+These are popular packages so your distro will probably have them.
+
+### Ubuntu
+
+```bash
+sudo apt install certbot python3-certbot-nginx nginx
+```
+
+### Arch
+
+```bash
+sudo pacman -S certbot certbot-nginx nginx
+```
+
+### OpenSuse
+
+```bash
+sudo zypper install nginx python3-certbot python3-certbot-nginx
+```
+
+## Configure GoToSocial
+
+In your GoToSocial config turn off letsencrypt.
+First open the file in your text editor.
+
+```bash
+sudoedit /gotosocial/config.yaml
+```
+
+Then set `letsencrypt-enabled: false`.
+
+If GoToSocial is already running, restart it.
+
+```bash
+sudo systemctl restart gotosocial.service
+```
+
+Or if you don't have a systemd service just restart it manually.
+
+## Set up nginx
+
+First we will set up nginx to serve GoToSocial as unsecured http and then later use certbot to automatically upgrade to https.
+Please do not try to use it until that's done or you'll be transmitting passwords over clear text.
+
+First we'll write a configuration for nginx and put it in `/etc/nginx/sites-available`.
+
+```bash
+sudo mkdir /etc/nginx/sites-available/
+sudoedit /etc/nginx/sites-available/yourgotosocial.url.conf
+```
+
+The file you're about to create should look a bit like this:
+
+```nginx.conf
+server {
+  listen 80;
+  server_name example.com;
+  location / {
+    proxy_pass http://localhost:8080;
+    proxy_set_header Host $host;
+  }
+}
+```
+
+Change `proxy_pass` to the ip and port that you're actually serving GoToSocial on and change `server_name` to your own domain name.
+If your domain name is `gotosocial.example.com` then `server_name gotosocial.example.com;` would be the correct value.
+If you're running GoToSocial on another machine with the local ip of 192.168.178.69 and on port 8080 then `proxy_pass http://192.168.178.69:8080;` would be the correct value.
+
+Next we'll need to link the file we just created to the folder that nginx reads configurations for active sites from.
+
+```bash
+sudo mkdir /etc/nginx/sites-enabled
+sudo ln -s /etc/nginx/sites-available/yourgotosocial.url.conf /etc/nginx/sites-enabled/
+```
+
+Now check for configuration errors.
+
+```bash
+sudo nginx -t
+```
+
+If everything is fine you should get this as output:
+
+```
+nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
+nginx: configuration file /etc/nginx/nginx.conf test is successful
+```
+
+Everything working? Great! Then restart nginx to load your new config file.
+
+```bash
+sudo systemctl restart nginx
+```
+
+## Setting up SSL with certbot
+
+You should now be able to run certbot and it will guide you through the steps required to enable https for your instance.
+
+```bash
+sudo certbot --nginx
+```
+
+After you do, it should have automatically edited your configuration file to enable https.
+Just reload it one last time and after that you should be good to go!
+
+```bash
+sudo systemctl restart nginx
+```
