 8. Run following commands to run the containers:
 ```bash
-docker compose -f docker-compose.<dev/prod>.yml up --build
+docker compose -f docker-compose.<dev/prod>.yml up
 ```
 
 The application is now deployed and the website should be accessible via http (`dev`) or https (`prod`). The images will be automatically updated on each 
 release and the containers restarted accordingly via [Watchtower](https://github.com/containrrr/watchtower).
 
 Note that this also means that it is currently not possible to have multiple Frontend instances deployed that talk to different backend instances.
-To achieve that, the Frontend instances each need to be manually built and deployed with the correct environment variables.

+## Renewing Certificates
+
+1. ssh into the server, e.g. `ssh manager@139.162.170.6 -i .ssh/bp_server`
+2. free up port 80 by stopping website: `sudo docker-compose -f docker-compose.yml down`
+3. run certbot: ` sudo certbot certonly --nginx -d klinik-dps.de -d www.klinik-dps.de`
+4. kill nginx: `sudo pkill nginx` (yeah it's in a weird state at this point and needs to be killed that way, don't ask me why)
+5. restart website: `sudo docker-compose -f docker-compose.yml up`
+
+If you run into problems:
+
+1. Check if port 80 is in use by something else: `netstat -antp`
+2. Allow http in firewall if necessary: `firewall-cmd --permanent --add-service=http` and `firewall-cmd --reload`
+3. Make sure nginx config is fine (should be located in `/etc/nginx/conf.d`):
+
+```
+server {
+    listen 80;
+    server_name klinik-dps.de www.klinik-dps.de;
+
+    root /usr/share/nginx/html;  # Base directory for web content
+    index index.html;
+
+    location /.well-known/ {
+        try_files $uri $uri/ =404;
+    }
+}
