 Useful for people who can't be fucked to just search for it on [GunCAD Index](https://guncadindex.com).
 
+### How It Works
+
+1. Go to the site and type a search query
+2. Click **Search on GCI** for a direct search, or **I'm feeling free** for a random result
+3. Copy the generated link and send it to whoever needs to learn how to use a search bar
+4. When they open the link, a fake cursor animates across the screen, types the query into the search box, clicks the button, and redirects them to GunCAD Index with a snarky "Was that so hard?" toast
+
 ### Development
 
 ```bash
+npm install
 npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
 ```
 
 Development server opens on [localhost:5000](http://localhost:5000)
+
+### Deployment
+
+#### Build
+
+```bash
+npm install
+npm run build
+```
+
+#### systemd
+
+Copy the service file and start it:
+
+```bash
+cp lmgcitfy.service /etc/systemd/system/
+systemctl daemon-reload
+systemctl enable --now lmgcitfy
+```
+
+The service expects the app to be located at `/opt/lmgcitfy` and runs as `www-data`. Adjust `WorkingDirectory` and `User`/`Group` in the service file as needed.
+
+#### NGINX
+
+Copy the config and enable it:
+
+```bash
+cp lmgcitfy.nginx.conf /etc/nginx/sites-available/lmgcitfy
+ln -s /etc/nginx/sites-available/lmgcitfy /etc/nginx/sites-enabled/
+nginx -t
+systemctl reload nginx
+```
+
+Replace `example.com` in the config with your domain. SSL certificates are expected at the default certbot paths — run `certbot --nginx -d yourdomain.com` if you need to generate them.
